Nursing education is a process aimed both at theoretical knowledge and skill development. The Fundamentals of Nursing is a course that furnishes students with professional knowledge, concepts and technical skills, and, also, is the keystone of nursing education in our country. Students experience a great deal of anxiety as they face basic nursing practices for the first time. Studies have revealed the effectiveness of music in relieving anxiety in many patient groups. However, no previous studies were found where music was used with the intent to lower the anxiety that students experience over the course of skill learning. The experimental study is aimed at determining the effect of music in decreasing anxiety during the first nursing practices of students in a laboratory setting. The experimental study was conducted on nursing students of Akdeniz University attending Fundamentals of Nursing, a freshman course, during the 2013-2014 academic year. A total of 73 students, of which 34 were assigned to the experimental group and 39 to the control group, participated in the study. Data collection was carried out using (a) the student identification form prepared by the authors, (b) skill control lists and (c) the Situational Anxiety Scale. The students in the experimental group listened to music during blood draw skill practice in a laboratory environment. The students were assessed with respect to their performance of blood drawing through skill control lists using the statements "True", "False" and "Forgotten". The anxiety levels and vital signs of students were assessed before and after the practice. The mean age of the students was 19.08. 64.7% of the experimental group and 82.1% of the control group were female. The age group of 64.7% of the students in the experimental group was female. The age group of 82.1% of the students in the control group was female. After music listening, the mean anxiety score of the students was 38.70±3.83 in the experimental group and

2012-09-01

Full Text Available This essay draws on definitions of gesture (Giorgio Agamben and Peter Brooks and catachresis (Peter Brooks, Jacques Derrida to examine the primacy of non-verbal signifiers as communicators of meaning in AMC’s Mad Men. Beginning with an analysis of Mad Men’s credit sequence, it draws attention to Mad Men’s use of gesture and catachresis in relation to melodrama’s privileging of non-verbal and naturalistic expression and its persistence as an intermedial mode that has moved back and forth between various media (theatre, novel, cinema, television and now digital formats. It argues that Mad Men’s melodramatic aesthetic is one that obliquely, and via a gestural and rhetorical ‘turned back’, communicates its relation to the past and the present.

ANALYSIS OF CHIP FORMATION DURING HARD TURNING THROUGH ACOUSTIC EMISSION

Full Text Available The paper deals with analysis of chip formation and related aspects of the chip formation during turning hardened steel 100Cr6. The paper draws a comparison of some aspects of the chip formation between turning annealed and hardened roll bearing steel. The results of the analysis show that there is the formation of a segmented chip in the case of hard turning. Frequency of segmentation is very high. A conventional piezoelectric dynamometer limits the frequency response to about 3.5 kHz. On the other hand, the frequency of process fluctuation may by obtained by using accelerometers or acoustic emission. This paper reports about the dynamic character of cutting process when hard turning and correlation among the calculated segmentation frequencies and the experimental analysis.

Constrained Convolutional Sparse Coding for Parametric Based Reconstruction of Line Drawings

KAUST Repository

Shaheen, Sara

2017-12-25

Convolutional sparse coding (CSC) plays an essential role in many computer vision applications ranging from image compression to deep learning. In this work, we spot the light on a new application where CSC can effectively serve, namely line drawing analysis. The process of drawing a line drawing can be approximated as the sparse spatial localization of a number of typical basic strokes, which in turn can be cast as a non-standard CSC model that considers the line drawing formation process from parametric curves. These curves are learned to optimize the fit between the model and a specific set of line drawings. Parametric representation of sketches is vital in enabling automatic sketch analysis, synthesis and manipulation. A couple of sketch manipulation examples are demonstrated in this work. Consequently, our novel method is expected to provide a reliable and automatic method for parametric sketch description. Through experiments, we empirically validate the convergence of our method to a feasible solution.

Cutting costs without drawing blood.

Science.gov (United States)

Copeland, T

2000-01-01

When looking for ways to cut costs, most managers reach for the head-count hatchet, and the markets usually roar with approval. But a company can almost always create far more sustainable value by rigorously evaluating the small-ticket capital items that often get rubber-stamped. Drawing on his experience as a consultant and providing numerous anecdotes, the author contends that those "little" requests often prove to be gold plated or unnecessary. A disciplined evaluation involves asking only eight questions and conducting postmortems--regular audits of units' capital spending. But the payoff is enormous. Because cutting the capital budget increases cash flow, the author argues that a permanent cut of just 15% in the planned level of capital spending could boost some companies' market capitalization by as much as 30%. The first three questions--Is this your investment to make? Does it really have to be new? How are our competitors meeting compliance needs?--are asked of operating managers as they assemble capital project requests. The next three are asked by senior managers of themselves and their colleagues as they examine proposals: Is the left hand duplicating investments made by the right? Are trade-offs between profit and capital spending well understood? Are there signs of budget massage? At the end of the review process, senior managers ask: Are we fully using shared assets? How fine-grained are our capacity measures? The author's suggestions for the postmortem include searching for systematic problems with whole classes of expenditures and making sure audit teams come up with specific recommendations for change.

Drawing experts have better visual memory while drawing.

Science.gov (United States)

Perdreau, Florian; Cavanagh, Patrick

2015-01-01

Drawing involves frequent shifts of gaze between the original and the drawing and visual memory helps compare the original object and the drawing across these gaze shifts while creating and correcting the drawing. It remains unclear whether this memory encodes all of the object or only the features around the current drawing position and whether both the original and the copy are equally well represented. To address these questions, we designed a "drawing" experiment coupled with a change detection task. A polygon was displayed on one screen and participants had to copy it on another, with the original and the drawing presented in alternation. At unpredictable moments during the copying process, modifications were made on the drawing and the original figure (while they were not in view). Participants had to correct their drawing every time they perceived a change so that their drawing always matched the current original figure. Our results show a better memory representation of the original figure than of the drawing, with locations relevant to the current production most accurately represented. Critically, experts showed better memory for both the original and the drawing than did novices, suggesting that experts have specialized advantages for encoding visual shapes.

DrawFromDrawings: 2D Drawing Assistance via Stroke Interpolation with a Sketch Database.

Science.gov (United States)

Matsui, Yusuke; Shiratori, Takaaki; Aizawa, Kiyoharu

2017-07-01

We present DrawFromDrawings, an interactive drawing system that provides users with visual feedback for assistance in 2D drawing using a database of sketch images. Following the traditional imitation and emulation training from art education, DrawFromDrawings enables users to retrieve and refer to a sketch image stored in a database and provides them with various novel strokes as suggestive or deformation feedback. Given regions of interest (ROIs) in the user and reference sketches, DrawFromDrawings detects as-long-as-possible (ALAP) stroke segments and the correspondences between user and reference sketches that are the key to computing seamless interpolations. The stroke-level interpolations are parametrized with the user strokes, the reference strokes, and new strokes created by warping the reference strokes based on the user and reference ROI shapes, and the user study indicated that the interpolation could produce various reasonable strokes varying in shapes and complexity. DrawFromDrawings allows users to either replace their strokes with interpolated strokes (deformation feedback) or overlays interpolated strokes onto their strokes (suggestive feedback). The other user studies on the feedback modes indicated that the suggestive feedback enabled drawers to develop and render their ideas using their own stroke style, whereas the deformation feedback enabled them to finish the sketch composition quickly.

A cohort study was planned to evaluate vaccine immunogenicity and effect of malaria and helminth co-infections on the bivalent Human papilloma virus (HPV) vaccine. The study would involve self collected introital swabs, blood draws and stool sample collection. We therefore conducted a pilot study to assess the acceptability of these procedures among the students and their parents. A cross-sectional study among forty four students from two purposively selected primary schools of Western Uganda. Exit interviews and two focus group discussions (FGD) (for parents) were conducted. Acceptability was measured by willingness to undergo the procedures again, recommending the procedures to others as well as proportion of introital swabs positive for β globulin. FGD determined acceptability of the parents and explored opinions and perceptions that would influence their decisions. HPV-16/18 and β globulin deoxyribonucleic acid (DNA) were analysed using a polymerase chain reaction (PCR) kit. All the students (100%) in the study were willing to provide a self- collected introital swab and a stool sample as well as recommending their friends while (86.3%) were willing for blood draws. There were 40/44 (90.1%) self collected introital swabs that had positive result for human β globulin though none of them was positive for HPV-16/18. In the FGD, it emerged that parents concerns were on the blood draws and introital swab collection which were addressed. The study procedures were highly acceptable among this study population of students and their parents. Follow-up to assess HPV vaccine effectiveness and factors that may influence the vaccine in this age group is feasible.

Lee, Tai-Hua; Wu, Fong-Gong; Chen, Huei-Tsz

2017-04-01

Focusing on the theme of direct manipulation, in this study, we proposed a new and innovative tangible user interface (TUI) design concept for a manipulative digital drawing pen. Based on interviews with focus groups brainstorming and experts and the results of a field survey, we selected the most suitable tangible user interface for children between 4 and 7 years of age. Using the new tangible user interface, children could choose between the brush tools after touching and feeling the various patterns. The thickness of the brush could be adjusted by changing the tilt angle. In a subsequent experimental process we compared the differences in performance and subjective user satisfaction. A total of sixteen children, aged 4-7 years participated in the experiment. Two operating system experiments (the new designed tangible digital drawing pen and traditional visual interface-icon-clicking digital drawing pens) were performed at random and in turns. We assessed their manipulation performance, accuracy, brush stroke richness and subjective evaluations. During the experimental process we found that operating functions using the direct manipulation method, and adding shapes and semantic models to explain the purpose of each function, enabled the children to perform stroke switches relatively smoothly. By using direct manipulation digital pens, the children could improve their stroke-switching performance for digital drawing. Additionally, by using various patterns to represent different brushes or tools, the children were able to make selections using their sense of touch, thereby reducing the time required to move along the drawing pens and select icons (The significant differences (p = 0.000, p drawing thick lines using the crayon function of the two (new and old) drawing pens (new 5.8750 drawing operations enhanced the drawing results, thereby increasing the children's enjoyment of drawing with tangible digital drawing pens.

Drawing cure: children's drawings as a psychoanalytic instrument.

Science.gov (United States)

Wittmann, Barbara

2010-01-01

This essay deals with the special case of drawings as psychoanalytical instruments. It aims at a theoretical understanding of the specific contribution made by children's drawings as a medium of the psychical. In the influential play technique developed by Melanie Klein, drawing continuously interacts with other symptomatic (play) actions. Nonetheless, specific functions of drawing within the play technique can be identified. The essay will discuss four crucial aspects in-depth: 1) the strengthening of the analysis's recursivity associated with the graphic artifact; 2) the opening of the analytic process facilitated by drawing; 3) the creation of a genuinely graphic mode of producing meaning that allows the child to develop a "theory" of the workings of his own psychic apparatus; and 4) the new possibilities of symbolization associated with the latter. In contrast to classical definitions of the psychological instrument, the child's drawing is a weakly structured tool that does not serve to reproduce psychic processes in an artificial, controlled setting. The introduction of drawing into the psychoanalytic cure is by no means interested in replaying past events, but in producing events suited to effecting a transformation of the synchronic structures of the unconscious.

But design and drawing are inseparably linked in ways which often go unnoticed. Essentially, it is very difficult, if not impossible, to conceive of a design...... is that computers can represent graphic ideas both faster and better than most medium-skilled draftsmen, drawing in design is not only about representing final designs. In fact, several steps involving the capacity to draw lie before the representation of a final design. Not only is drawing skills an important...... prerequisite for learning about the nature of existing objects and spaces, and thus to build a vocabulary of design. It is also a prerequisite for both reflecting and communicating about design ideas. In this paper, a taxonomy of notation, reflection, communication and presentation drawing is presented...

Full Text Available The goal of the research is to produce an application, which can detect malaria on patient through microscopic digital image of blood sample. The research methods are data collection, design analysis, testing and evaluation. The used application methods are image pre-processing, morphology and image segmentation using OpenCV. The expected result is a creation of application, which can be able to detect malaria on a microscopic digital image of patient blood sample. The conclusion is that the application can detect malaria from young trophozoites stadium and gametesocytes from the picture.Keywords: Detection; Malaria; Computer Vision; OpenCVINTRODUCTIONSystem technology of computer-based with artificial intelligence already can be used in medicine field, for example, to resolve the problems: detecting specific disease and its symptoms, analyzing the content of a sample, monitoring the condition of an organ, and others. Nevertheless, the medical field is very wide, so for detecting diseases problems, not yet much disease that detection can be done with a computer-based system. One example of the issues is well-known disease detection, which is malaria. Malaria is classified as a serious disease because it can cause death if it is not treated properly. Malaria has various types and can affect anyone anywhere. The symptoms of malaria is really common as it may appear in daily life, but cannot always indicate that a person infected with malaria. Indications, which can show that a person infected with malaria, are the clinical examination and blood tests.With the blood test, the treatment of malaria can be implemented correctly and precisely. It needs technology that can detect malaria correctly and precisely. The solution is the method of support vector machine that can detect malaria in humans by viewing image of appearance blood cells.METHODThe methods used in this research are data collection, analysis and design.

Full Text Available This paper sets view to consider the significance of drawings as part of visual communication design. Drawing gives a chance to observe, to muse, to select and develop continuous thinking techniques. It is to present that drawing is not just a cursory to generate ideas, but it has its own energy and philosophy which deserve studying as a domain of art. In recent years, drawing has received attention; there is on the one hand a group of drawing practitioners, and on the other hand a group of drawing researchers. Drawing in design is a medium of visual and spatial thinking. Digging into research actually is a necessity for visual communication studies. It is suggested here three kinds of research approaches: research into art/design; research through art/design; and research for art/design. Indeed, it leads to four axis topics (topoi for design studies: design practice, design product, design discourse, and design meta-discourse. A field of study called ‘visual culture’ which, departed from the study of critical theory and cultural studies which have set out relatively new field of study called ‘visual studies’. Based upon to this perspective, visual (communication studies should be more self-reflexive. The production of visual communication contributes to construct the visual culture in society.

The ATF damping ring has been upgraded with new read-out electronics for the beam position monitors (BPM), capable to acquire the beam orbits on a turn-by-turn basis, as well as in a high resolution averaging mode. The new BPM system allows to improve optic corrections and to achieve an even smaller vertical emittance (<2pm). Experimental results are presented based on turn-by-turn beam orbit measurements in the ring, for estimating the β functions and dispersion along the lattice. A fast method to measure spectral line amplitude in a few turns is also presented, including the evaluation of chromaticity.

How to Draw Energy Level Diagrams in Excitonic Solar Cells.

Science.gov (United States)

Zhu, X-Y

2014-07-03

Emerging photovoltaic devices based on molecular and nanomaterials are mostly excitonic in nature. The initial absorption of a photon in these materials creates an exciton that can subsequently dissociate in each material or at their interfaces to give charge carriers. Any attempt at mechanistic understanding of excitonic solar cells must start with drawing energy level diagrams. This seemingly elementary exercise, which is described in textbooks for inorganic solar cells, has turned out to be a difficult subject in the literature. The problem stems from conceptual confusion of single-particle energy with quasi-particle energy and the misleading practice of mixing the two on the same energy level diagram. Here, I discuss how to draw physically accurate energy diagrams in excitonic solar cells using only single-particle energies (ionization potentials and electron affinities) of both ground and optically excited states. I will briefly discuss current understanding on the electronic energy landscape responsible for efficient charge separation in excitonic solar cells.

- Hemolysis of emergency department blood samples is a common occurrence and has a negative impact on health care delivery. - To determine the effect of preanalytic factors (straight stick, intravenous [IV] line, needle gauge, location of blood draw, syringe versus vacuum tube use, tourniquet time) on hemolysis in emergency department blood samples. - A single 65 000-visit emergency department's electronic health record was queried for emergency department potassium results and blood draw technique for all samples obtained in calendar year 2014, resulting in 54 531 potassium results. Hemolyzed potassium was measured by hemolysis index. Comparisons of hemolysis by sampling technique were conducted by χ 2 tests. - Overall hemolysis was 10.0% (5439 of 54 531). Hemolysis among samples obtained from straight stick was significantly less than among those obtained with IV line (5.4% [33 of 615] versus 10.2% [4821 of 47 266], P < .001). For IV-placed blood draws, antecubital location had a statistically significant lower overall hemolysis compared with other locations: 7.4% (2117 of 28 786) versus 14.6% (2622 of 17 960) ( P < .001). For blood drawn with a syringe compared with vacuum, hemolysis was 13.0% (92 of 705) and 11.0% (1820 of 16 590), respectively ( P = .09, not significant). For large-gauge IV blood draws versus smaller-gauge IV lines, a lower hemolysis was also observed (9.3% [3882 of 41 571] versus 16.7% [939 of 5633]) ( P < .001). For IV-drawn blood with tourniquet time less than 60 seconds, hemolysis was 10.3% (1362 of 13 162) versus 13.9% for more than 60 seconds (532 of 3832), P < .001. - This study confirmed previous findings that straight stick and antecubital location are significantly associated with reduced hemolysis and indicated that shorter tourniquet time and larger gauge for IV draws were significantly associated with lower hemolysis.

Nowadays, an increasing demand for small metal parts in electronic and automotive industries can be observed. Deep drawing is a well-suited technology for the production of such parts due to its excellent qualities for mass production. However, the downscaling of the forming process leads to new challenges in tooling and process design, such as high relative deviation of tool geometry or blank displacement compared to the macro scale. FEM simulation has been a widely-used tool to investigate the influence of symmetrical process deviations as for instance a global variance of the drawing radius. This study shows a different approach that allows to determine the impact of asymmetrical process deviations on micro deep drawing. In this particular case the impact of an asymmetrical drawing radius deviation and blank displacement on cup geometry deviation was investigated for different drawing ratios by experiments and FEM simulation. It was found that both variations result in an increasing cup height deviation. Nevertheless, with increasing drawing ratio a constant drawing radius deviation has an increasing impact, while blank displacement results in a decreasing offset of the cups geometry. This is explained by different mechanisms that result in an uneven cup geometry. While blank displacement leads to material surplus on one side of the cup, an unsymmetrical radius deviation on the other hand generates uneven stretching of the cups wall. This is intensified for higher drawing ratios. It can be concluded that the effect of uneven radius geometry proves to be of major importance for the production of accurately shaped micro cups and cannot be compensated by intentional blank displacement.

2016-07-01

Researchers in the mind sciences often look to the production and analysis of drawings to reveal the mental processes of their subjects. This essay presents three episodes that trace the emergence of drawing as an instrumental practice in the study of the mind. Between 1880 and 1930, drawings gained currency as a form of scientific evidence - as stable, reproducible signals from a hidden interior. I begin with the use of drawings as data in the child study movement, move to the telepathic transmission of drawings in psychical research and conclude with the development of drawing as an experimental and diagnostic tool for studying neurological impairment. Despite significant shifts in the theoretical and disciplinary organisation of the mind sciences in the early twentieth century, researchers attempted to stabilise the use of subject-generated drawings as evidence by controlling the contexts in which drawings were produced and reproduced, and crafting subjects whose interiority could be effectively circumscribed. While movements such as psychoanalysis and art therapy would embrace the narrative interpretation of patient art, neuropsychology continued to utilise drawings as material traces of cognitive functions.

Full Text Available In this article we will discuss how the aesthetic values, that the digital imaging provide, has influenced in drawing and architecture in a historical reading of the evolution of each means of architecture expression. In painting art and photography have been happening genres and styles that have adopted criteria of one or another discipline. When photography became independent from painting as an artistic discipline, its relationship to the architecture affected both the acceptance of its stylistic canon and the broadcast area. With technological development and the emergence of the new concept of digital imaging, it has become an indispensable tool in the whole process of contemporary architecture, which should not contaminate the true sense of the architectural drawing.

Drawing Theory. An Introduction

Directory of Open Access Journals (Sweden)

Stefano Milani

2014-08-01

Full Text Available Nowadays, drawing practices seem to operate in a rather uncertain field that is typical of an in-between phase of disciplinary development and that needs to be addressed, if an ‘anticipated projection’ of the development of drawing is to be attempted. The field of drawing, as practice and discourse, seems to have entered an end-condition, where the celebration of the extensive production of drawings is combined with a certain fatigue in both its understanding and reflection. Even though the role of drawing is nowadays still regarded as the most common act of architecture, this understanding of drawing is hardly subject to critical inquiries, and, unfortunately, mostly limited to its instrumental role within the representation of the project.A common characteristic in all of the papers in this issue of Footprint is that a specific character of the theoretical field generated by drawing is the elaboration of the correlation between two epistemic regions. This singular character probably belongs to drawing’s structural duality of being simultaneously a simulacrum of a reality and reality itself, memory and anticipation, subject and object, by being in essence the measure of two different facets inherent to architectural thinking. Drawing not only gives consistency to the poles, rendering them architectural matter, but also literally (reconstructs them. At the same time, drawing formalizes the theoretical distance between the two.

Hospitalized children drawing their pain: the contents and cognitive and emotional characteristics of pain drawings.

Kortesluoma, Riitta-Liisa; Punamäki, Raija-Leena; Nikkonen, Merja

2008-12-01

Describing pain is difficult. Children like to draw, and through their drawing they reveal worrying issues. This study aimed to examine how hospitalized children express pain through drawings, and was carried out by examining children's thematic drawings of pain. A comparison was made between hospitalized children and healthy control groups with respect to the thematic contents and cognitive and emotional characteristics of pain drawings. The drawings were sorted in categories on the basis of content, and cognitive competence and emotional disturbances by the Draw-a-Person procedure. The hospitalized children showed a lower level of cognitive capacity than their healthy controls. The control group children revealed a higher level of emotional disturbance than the hospitalized children. The groups differed in the contents of their drawings. The drawings of the hospitalized children frequently depicted medical procedures, whereas the drawings of the healthy controls depicted more consoling human and family relations.

Revealing the sketching sequence of a line drawing can be visually intriguing and used for video-based storytelling. Typically this is enabled based on tedious recording of artists\\' drawing process. We demonstrate that it is often possible to estimate a reasonable drawing order from a static line drawing with clearly defined shape geometry, which looks plausible to a human viewer. We map the key principles of drawing order from drawing cognition to computational procedures in our framework. Our system produces plausible animated constructions of input line drawings, with no or little user intervention. We test our algorithm on a range of input sketches, with varying degree of complexity and structure, and evaluate the results via a user study. We also present applications to gesture drawing synthesis and drawing animation creation especially in the context of video scribing.

Essential Drawings: Are those drawings identified by the facility staff as necessary to directly support the safe operation of the facility or equipment (HNF 1997a). Support Drawings: Are those drawings identified by facility staff that further describe the design details of structures, systems, or components shown on essential drawings. (HNF 1997a) The Characterization equipment drawings identified in this report are deemed essential drawings as defined in HNF-PRO-242, Engineering Drawing Requirements (HNF 1997a). These drawings will be prepared, revised, and maintained per HNF-PRO-440, Engineering Document Change Control (HNF 1997b). All other Characterization equipment drawings not identified in this document will be considered General drawings until the Characterization Equipment Drawing Evaluation Report (Wilson 1998) is updated during fiscal year 1999. Trucks 1 and 2 drawings are not included in this revision of the essential drawing list due to uncertainty about future use

[Traces of blood. The significance of blood in criminology at the turn of the 19th century].

Science.gov (United States)

Bachhiesl, Christian

2010-03-01

In late 19th and early 20th century, criminology became institutionalized as an independent branch of science. Methodologically it focused on the 'exact' methods of the natural sciences, but also it tried to integrate the methods of the humanities. This mix of methods becomes visible in the treatment of blood, which on the one hand was an object of then brand new methods of scientific analysis (identification of human blood by the biological or precipitin method), and on the other hand was analyzed as a product of the magic and superstitious mentalities of criminals. The methodical tension resulting from this epistemological crossbreeding did not disturb the criminologists, for whom the reconciliation of opposite ways of thinking and researching seemed to be possible. In this encyclopaedic analysis of blood early criminology tried to combine the anthropological exploration of vampirism with the chemical and microscopic detection of antibodies and haemoglobin, thus mirroring the positivistic optimism that was then prevalent.

Drawing-to-Learn: A Framework for Using Drawings to Promote Model-Based Reasoning in Biology

Quillin, Kim; Thomas, Stephen

2015-01-01

The drawing of visual representations is important for learners and scientists alike, such as the drawing of models to enable visual model-based reasoning. Yet few biology instructors recognize drawing as a teachable science process skill, as reflected by its absence in the Vision and Change report’s Modeling and Simulation core competency. Further, the diffuse research on drawing can be difficult to access, synthesize, and apply to classroom practice. We have created a framework of drawing-to-learn that defines drawing, categorizes the reasons for using drawing in the biology classroom, and outlines a number of interventions that can help instructors create an environment conducive to student drawing in general and visual model-based reasoning in particular. The suggested interventions are organized to address elements of affect, visual literacy, and visual model-based reasoning, with specific examples cited for each. Further, a Blooming tool for drawing exercises is provided, as are suggestions to help instructors address possible barriers to implementing and assessing drawing-to-learn in the classroom. Overall, the goal of the framework is to increase the visibility of drawing as a skill in biology and to promote the research and implementation of best practices. PMID:25713094

The Turn to Precarity in Twenty-First Century Fiction

Directory of Open Access Journals (Sweden)

Morrison Jago

2014-01-01

Full Text Available Recent years have seen several attempts by writers and critics to understand the changed sensibility in post-9/11 fiction through a variety of new -isms. This essay explores this cultural shift in a different way, finding a ‘turn to precarity’ in twenty-first century fiction characterised by a renewal of interest in the flow and foreclosure of affect, the resurgence of questions about vulnerability and our relationships to the other, and a heightened awareness of the social dynamics of seeing. The essay draws these tendencies together via the work of Judith Butler in Frames of War, in an analysis of Trezza Azzopardi’s quasi-biographical study of precarious life, Remember Me.

Chan, Zenobia C Y

2013-08-01

The implementation of art education in nursing is said to have positive effects on nursing students. Most studies applied visual art dialogues or object design, whereas the effectiveness of drawing as a teaching and learning method is rarely examined and discussed. This paper aimed to discuss the potential and effectiveness of drawing as a learning and teaching method. Four drawings which were created by Hong Kong nursing students are demonstrated and the students' perspectives of how drawing enhanced learning are shown in this paper. Topics on drawing as a fun teaching and learning method and the way it can enhance critical thinking and creativity are also discussed. In conclusion, the activity was a great success, and students enjoyed the learning process and reflected positive comments. However, we cannot conclude that drawing is an effective teaching and learning method based on a single paper, therefore more similar studies should be conducted to investigate this method.

Drawing cartoon faces--a functional imaging study of the cognitive neuroscience of drawing.

Science.gov (United States)

Miall, R Chris; Gowen, Emma; Tchalenko, John

2009-03-01

We report a functional imaging study of drawing cartoon faces. Normal, untrained participants were scanned while viewing simple black and white cartoon line drawings of human faces, retaining them for a short memory interval, and then drawing them without vision of their hand or the paper. Specific encoding and retention of information about the faces were tested for by contrasting these two stages (with display of cartoon faces) against the exploration and retention of random dot stimuli. Drawing was contrasted between conditions in which only memory of a previously viewed face was available versus a condition in which both memory and simultaneous viewing of the cartoon were possible, and versus drawing of a new, previously unseen, face. We show that the encoding of cartoon faces powerfully activates the face-sensitive areas of the lateral occipital cortex and the fusiform gyrus, but there is no significant activation in these areas during the retention interval. Activity in both areas was also high when drawing the displayed cartoons. Drawing from memory activates areas in posterior parietal cortex and frontal areas. This activity is consistent with the encoding and retention of the spatial information about the face to be drawn as a visuo-motor action plan, either representing a series of targets for ocular fixation or as spatial targets for the drawing action.

Since automated CAD drawing generation systems still require human intervention, improvements were focussed on an interactive processing section (data input and correcting operation) which necessitates a vast amount of work. As a result, human intervention was eliminated, the original objective of a computerized system. This is the first step taken towards complete automation. The effects of development and commercialization of the system are as described below. (1) The interactive processing time required for generating drawings was improved. It was determined that introduction of the CAD system has reduced the time required for generating drawings. (2) The difference in skills between workers preparing drawings has been eliminated and the quality of drawings has been made uniform. (3) The extent of knowledge and experience demanded of workers has been reduced. (author)

Crack turning in integrally stiffened aircraft structures

Science.gov (United States)

Pettit, Richard Glen

Current emphasis in the aircraft industry toward reducing manufacturing cost has created a renewed interest in integrally stiffened structures. Crack turning has been identified as an approach to improve the damage tolerance and fail-safety of this class of structures. A desired behavior is for skin cracks to turn before reaching a stiffener, instead of growing straight through. A crack in a pressurized fuselage encounters high T-stress as it nears the stiffener---a condition favorable to crack turning. Also, the tear resistance of aluminum alloys typically varies with crack orientation, a form of anisotropy that can influence the crack path. The present work addresses these issues with a study of crack turning in two-dimensions, including the effects of both T-stress and fracture anisotropy. Both effects are shown to have relation to the process zone size, an interaction that is central to this study. Following an introduction to the problem, the T-stress effect is studied for a slightly curved semi-infinite crack with a cohesive process zone, yielding a closed form expression for the future crack path in an infinite medium. For a given initial crack tip curvature and tensile T-stress, the crack path instability is found to increase with process zone size. Fracture orthotropy is treated using a simple function to interpolate between the two principal fracture resistance values in two-dimensions. An extension to three-dimensions interpolates between the six principal values of fracture resistance. Also discussed is the transition between mode I and mode II fracture in metals. For isotropic materials, there is evidence that the crack seeks out a direction of either local symmetry (pure mode I) or local asymmetry (pure mode II) growth. For orthotropic materials the favored states are not pure modal, and have mode mixity that is a function of crack orientation. Drawing upon these principles, two crack turning prediction approaches are extended to include fracture

Wojaczyńska-Stanek, Katarzyna; Koprowski, Robert; Wróbel, Zygmunt; Gola, Małgorzata

2008-02-01

Headache is a common health problem in childhood. Children's drawings are helpful in the diagnosis of headache type. Children, especially younger ones, communicate better through pictures than verbally. The aim of the present study is to evaluate the usefulness of drawings of the child's headache in the diagnostic process carried out by a pediatrician and a pediatric neurologist. At the beginning of a visit in a neurological clinic, or on the first day of hospitalization, the child was asked, "Please draw your headache," or "How do you feel your headache?" without any additional explanations or suggestions. Clinical diagnosis of headache type was made on the basis of the standard diagnostic evaluation. For the purpose of this study, children's headaches were categorized as migraine, tension-type headache, or "the others." One hundred twenty-four drawings of children with headaches were analyzed by 8 pediatricians and 8 pediatric neurologists. The analysts were unaware of the clinical history, age, sex, and diagnosis of the patients. The clinical diagnosis was considered the "gold standard" to which the headache drawing diagnosis was compared. There were 68 girls 5-18 years of age and 56 boys 7-18 years of age. Of the 124 children, 40 were clinically diagnosed with migraine (32.2%), 47 with tension-type headache (37.9%), and 37 (29.8%) as the others. Children with migraine most frequently draw sharp elements. Children with tension-type headache mainly drew compression elements and pressing elements. In the group of "the other" headaches, 21 children were diagnosed with somatoform disorders. The most frequent element in this group's drawings was a whirl in the head. Colors used most frequently were black and red, which signify severe pain. There was no difference in sensitivity of diagnoses between neurologists and pediatricians. Because the evaluation of drawings by children with headaches done both by pediatricians and pediatric neurologists was correct for

Hippo Draw is a result of research into finding better ways to visualize the kind of statistical data that is so common in high energy physics analyses. In these analyses, frequency distributions are visualized as histograms, contour plots, scatter plots, etc. Traditionally, one used a library of subroutines, called a histogram package, within one's analysis programs to create and display such distributions. HippoDraw is a NeXTstep application for viewing statistical data. It has several unique features which make viewing data distributions highly interactive. It also incorporates simple drawing tools. HippoDraw is written in Objective-C and uses the Hippoplotamus library package which handles the n-tuples and displays. Hippoplotamus is written in ANSI C. 4 refs

During fiscal year 1994, work was begun to label Tank Farm components and provide user friendly system based drawings for Tank Waste Remediation System (TWRS) operations and maintenance. During the first half of fiscal 1995, the field verification program continued to convert TWRS drawings into CAD format and verify the accuracy based on visual inspections. During the remainder of fiscal year 1995 these efforts will be combined into a single program providing system based drawings and field verification of TWRS equipment and facilities. This combined program for TWRS will include all active systems for tank farms. Operations will determine the extent of drawing and labeling requirements for single shell tanks, i.e. the electrical distribution, HVAC, leak detection, and the radiation monitoring system. The tasks required to meet these objectives, include the following: identify system boundaries or scope for drawing being verified; label equipment/components in the process systems with a unique Equipment Identification Number (EIN) per the TWRS Data Standard; develop system drawings that are coordinated by ''smart'' drawing numbers and/or drawing references as identified on H-14-020000; develop a Master Equipment List (MEL) multi-user data base application which will contain key information about equipment identified in the field; and field verify and release TWRS Operation and Maintenance (O and M) drawings

What Does the DAP:IQ Measure?: Drawing Comparisons between Drawing Performance and Developmental Assessments.

Science.gov (United States)

Rehrig, Gwendolyn; Stromswold, Karin

2018-01-01

Human figure drawing tasks such as the Draw-a-Person test have long been used to assess intelligence (F. Goodenough, 1926). The authors investigate the skills tapped by drawing and the risk factors associated with poor drawing. Self-portraits of 345 preschool children were scored by raters trained in using the Draw-a-Person Intellectual Ability test (DAP:IQ) rubric (C. R. Reynolds & J. A. Hickman, 2004). Analyses of children's fine motor, gross motor, social, cognitive, and language skills revealed that only fine motor skill was an independent predictor of DAP:IQ scores. Being a boy and having a low birth weight were associated with lower DAP:IQ scores. These findings suggest that although the DAP:IQ may not be a valid measure of cognitive ability, it may be a useful screening tool for fine motor disturbances in at-risk children, such as boys who were born at low birth weights. Furthermore, researchers who use human figure drawing tasks to measure intelligence should measure fine motor skill in addition to intelligence.

Broza, Georg; Castano, Victor M.; Martinez-Barrera, Gonzalo; Menard, Kevin P.; Simoes, Carla

2005-01-01

We have studied the copolymer of poly(ethylene terephthalate) (PET) with 0.6mole fraction of p-hydroxybenzoic acid (PHB). It is a longitudinal polymer liquid crystal (PLC). A number of otherwise identical samples were subjected to drawing to achieve in turn 20%, 40%, 60%, 80% and 100% increase in length. The drawing was performed isothermally at 60, 100 and 140 deg. C. Pressure-volume-temperature (P-V-T) results have been obtained for pressures up to 200Jcm -3 and temperatures up to 150 deg. C or so. Parameters of the Hartmann equation of state have been evaluated. Drawing first results in an increase in specific (and also free) volume, then in a decrease caused by increased orientation of the PLC, and finally in an apparent increase caused by the appearance of voids. The tensile modulus E has been determined for all pre-drawn samples. It reflects the volumetric changes a rebours: the initial increase in specific volume results in lower E values, orientation in E increase, and void formation in a second decrease

Sonia's mother was concerned about her 9-year old daughter's aggression, defiant behavior, and distractibility. When she was 4-years, she kicked her bother and he lost a tooth as a result of the trauma. At this time, her pediatrician was concerned about hyperactivity, impulsivity, and defiance of authority and recommended a psychological evaluation. Sonia's father refused an evaluation and responded by physically abusing his wife while demanding a transfer to a new physician. Sonia's mother left her husband at this time and moved away with Sonia. Spousal abuse occurred frequently before the separation, and Sonia may have been physically abused as well. Currently, Sonia is in third grade where she is underperforming in many areas. She enjoys drawing and reading, but struggles to sit quietly and stay on task. Her teacher reports frequent vocal and physical disruptions. Homework takes an inordinate amount of time to complete. She does not have a sustained friendship; her mother feels that this is because other kids do not like being bossed by Sonia. Her mother is concerned about Sonia's behavior especially the unremorseful disruptive behavior toward her younger brother and grandmother. Sonia was born after an uneventful full-term pregnancy without evidence of maternal smoking, drugs, alcohol, or medications. Motor and social developmental milestones were achieved at the appropriate time. Language milestones were achieved early; her mother recalls that Sonia learned to read at the age of 3 years. Sonia's medical history is significant for obesity, seasonal allergic rhinitis, and delayed sleep onset with prolonged awakenings associated with nightmares. Her mother reports that Sonia "worries about everything," including thoughts that her brother will turn into a monster. When an argument occurs at home, she "gets scared," bites her nails, and cries. Sonia currently lives with her mother, 2 younger brothers, step-father, and grandparents. Family history is significant for

The Translator's Turn: in the Cultural Turn

Institute of Scientific and Technical Information of China (English)

徐玮玮

2003-01-01

@@ Introduction: Douglas Robinson rose to the defense of the " atheoretical" American literary translator in The Translator's Turn (1991). Here, I borrowed the title from him, but I will write my paper in the thought of the translator's role in translating. In his book, Robinson argued that the literary translator embodies an integration of feeling and thought, of intuition and systematization. In analyzing the " turn" that the translator take from the source text to the target text, Robinson offered a " dialogical" model, that is the translator's dialogical engagement with the source language and with the ethic of the target language. Robinson allows for the translator to intervene, subvert, divert, even entertain, emphasizing the creative aspect of literary translation. The translation linguists, scientists, and philosophers have had their chance at translation theory; now it is time, he argued, for the literary translators to have their " turn".

"Some curious drawings". Mars through Giovanni Schiaparelli's eyes: between science and fiction.

Science.gov (United States)

Canadelli, Elena

2009-01-01

From the second half of the 19th century up to the first part of the 20th century the drawings of Mars by the Italian astronomer Giovanni Schiaparelli became the centre of an international controversy concerning the existence of canals and the hypothetical habitability of the red planet. These images also generated a full impact on the popular culture of the time. This essays follows the scientific representations of Mars by Schiaparelli (drawings of discs and maps) from their birth in the hands of the astronomy community up to their growing old in the hands of scientific popularizers such as Camille Flammarion and science fiction writers such as Herbert George Wells. With its seas and canyons Mars turned into the ideal background for scientific and exotic romanticism, offering a suitable setting for novels and tales. The core question crossed paths with the contemporary early 20th century debate raging on about the evolutionary theory. The study of Mars moved from astronomy to extraterrestrial physiology, biology, meteorology and geography: astronomical images then became imaginary portraits of Martians and artificial Martian landscapes.

Lattice modeling and calibration with turn-by-turn orbit data

Directory of Open Access Journals (Sweden)

Xiaobiao Huang

2010-11-01

Full Text Available A new method that explores turn-by-turn beam position monitor (BPM data to calibrate lattice models of accelerators is proposed. The turn-by-turn phase space coordinates at one location of the ring are first established using data from two BPMs separated by a simple section with a known transfer matrix, such as a drift space. The phase space coordinates are then tracked with the model to predict positions at other BPMs, which can be compared to measurements. The model is adjusted to minimize the difference between the measured and predicted orbit data. BPM gains and rolls are included as fitting variables. This technique can be applied to either the entire or a section of the ring. We have tested the method experimentally on a part of the SPEAR3 ring.

Drawing Contour Trees in the Plane.

Science.gov (United States)

Heine, C; Schneider, D; Carr, Hamish; Scheuermann, G

2011-11-01

The contour tree compactly describes scalar field topology. From the viewpoint of graph drawing, it is a tree with attributes at vertices and optionally on edges. Standard tree drawing algorithms emphasize structural properties of the tree and neglect the attributes. Applying known techniques to convey this information proves hard and sometimes even impossible. We present several adaptions of popular graph drawing approaches to the problem of contour tree drawing and evaluate them. We identify five esthetic criteria for drawing contour trees and present a novel algorithm for drawing contour trees in the plane that satisfies four of these criteria. Our implementation is fast and effective for contour tree sizes usually used in interactive systems (around 100 branches) and also produces readable pictures for larger trees, as is shown for an 800 branch example.

Continuous intra-arterial blood-gas monitoring

Science.gov (United States)

Divers, George A.; Riccitelli, Samuel D.; Blais, Maurice; Hui, Henry K.

1993-05-01

Fiber optic technology and optical fluorescence have made the continuous monitoring of arterial blood gases a reality. Practical products that continuously monitor blood gases by use of an invasive sensor are now available. Anesthesiologists and intensive care physicians are beginning to explore the practical implications of this technology. With the advent of intra- arterial blood gas monitors it is possible to assess arterial blood gas values without the labor intensive steps of drawing blood and transporting a blood sample to the lab followed by the actual analysis. These intra-arterial blood gas monitors use new optical sensor technologies that can be reduced in size to the point that the sensor can be inserted into the arterial blood flow through a 20-gauge arterial cannula. In the best of these technologies the sensors accuracy and precision are similar to those in vitro analyzers. This presentation focuses on background technology and in vivo performance of a device developed, manufactured, and marketed by Puritan-Bennett Corporation.

Direct friction measurement in draw bead testing

DEFF Research Database (Denmark)

Olsson, David Dam; Bay, Niels; Andreasen, Jan Lasson

2005-01-01

The application of draw beads in sheet metal stamping ensures controlled drawing-in of flange parts. Lubrication conditions in draw beads are severe due to sliding under simultaneous bending. Based on the original draw bead test design by Nine [1] comprehensive studies of friction in draw beads...... have been reported in literature. A major drawback in all these studies is that friction is not directly measured, but requires repeated measurements of the drawing force with and without relative sliding between the draw beads and the sheet material. This implies two tests with a fixed draw bead tool...... and a freely rotating tool respectively, an approach, which inevitably implies large uncertainties due to scatter in the experimental conditions. In order to avoid this problem a new draw bead test is proposed by the authors measuring the friction force acting on the tool radius directly by a build...

Economizing justice: Turning equity claims into lower energy tariffs in Chile

International Nuclear Information System (INIS)

Alvial-Palavicino, Carla; Ureta, Sebastián

2017-01-01

This paper considers the issue of how energy justice is economized; how political and ethical claims about particular energy (in)justices are turned into economic valuations. Drawing on science and technology studies, we present a conceptual framework that understands economization as emerging from three interrelated processes: problematization, framing and overflowing. Applying this framework to the drafting of new energy legislation in Chile, we trace how perceived shortcomings in equity and distributional justice were turned into “market failures,” able to be resolved by market-based mechanisms. This case highlights the dangers implicit in the uncritical economization of energy justice claims, in which ethical considerations regarding the distribution of risks and benefits of energy production and provision are reduced to a redistribution of payments among consumers – something that limits the possibilities for structural reform. - Highlights: • The implementation of an electricity equity tariff is discussed. • A process of economization transforms equity demands into market devices. • Energy justice, as mobilized in the policy process, includes multiple forms of justice. • Competition between these multiple forms fails to deliver a complete form of justice.

The French pioneer for blood transfusion, who eventually organized the very early blood transfusion centers worldwide, went to imagine a scenario written in purpose for Charlie Chaplin, the unique character of "The Tramp" ("Charlot" in French). The movie Star was offered to feature a blood donation propagandist, and no longer the perpetual, well-known, "loser". This anecdote, besides being amusing, tells a lot on how Arnault Tzank encompassed all the difficulties in collecting blood enough to meet the demand, at all times; his proposal turns out to be extremely modern and questions nowadays marketing for blood donation.

Mimicry by asx- and ST-turns of the four main types of beta-turn in proteins.

Science.gov (United States)

Duddy, William J; Nissink, J Willem M; Allen, Frank H; Milner-White, E James

2004-11-01

Hydrogen-bonded beta-turns in proteins occur in four categories: type I (the most common), type II, type II', and type I'. Asx-turns resemble beta-turns, in that both have an NH. . .OC hydrogen bond forming a ring of 10 atoms. Serine and threonine side chains also commonly form hydrogen-bonded turns, here called ST-turns. Asx-turns and ST-turns can be categorized into four classes, based on side chain rotamers and the conformation of the central turn residue, which are geometrically equivalent to the four types of beta-turns. We propose asx- and ST-turns be named using the type I, II, I', and II' beta-turn nomenclature. Using this, the frequency of occurrence of both asx- and ST-turns is: type II' > type I > type II > type I', whereas for beta-turns it is type I > type II > type I' > type II'. Almost all type II asx-turns occur as a recently described three residue feature named an asx-nest.

Turning breech babies after 34 weeks: the if, how, & when of turning breech babies.

Science.gov (United States)

Cohain, Judy Slome

2007-01-01

Techniques for turning a term breech baby are 1). External cephalic version (ECV) using hands and ultrasound only; 2). Acupuncture point stimulation, by needle or moxibustion; 3). Chiropractic "Webster" technique; 4). Hypnotherapy; and 5). Special exercises. Fifty % of breech fetuses at 34 weeks will turn by themselves to head down by 38 weeks. Therefore, to be considered effective, a technique for turning breech must turn the baby and keep it turned more than 50% of the time. Only ECV with an experienced practitioner has been documented to have a greater than 50% success rate at 37 weeks; in 95% of cases the head stays down. Most women experience the fetus turning by hand as quick but very painful. "Unstable lie" is sometimes used as a baseless excuse for inducing labor after the baby turns from breech to head down.

Expressive drawing ability in children with autism.

Science.gov (United States)

Jolley, Richard P; O'Kelly, Rachael; Barlow, Claire M; Jarrold, Christopher

2013-03-01

The autistic impairments in emotional and social competence, imagination and generating ideas predict qualitative differences in expressive drawings by children with autism beyond that accounted by any general learning difficulties. In a sample of 60 5-19-year-olds, happy and sad drawings were requested from 15 participants with non-savant autism and compared with those drawn by three control groups matched on either degree of learning difficulty (MLD), mental age (MA) or chronological age (CA). All drawings were rated by two artists on a 7-point quality of expression scale. Contrary to our predictions, the drawings from the autistic group were rated similar to those of the MA and MLD groups. Analysis of the people and social content of the drawings revealed that although children with autism did not draw fewer people, they did draw more immature forms than mental age controls. Furthermore, there was tentative evidence that fewer social scenes were produced by the autism sample. We conclude that the overall merit of expressive drawing in autism is commensurate with their general learning difficulties, but the social/emotional impairment in autism affects their drawings of people and social scenes. © 2013 The British Psychological Society.

To characterize the communication ritual in the pharmacist-customer dyad during a blood pressure measurement and counselling episode. A Portuguese urban community pharmacy. An exploratory, cross-sectional design was used. Participants were purposively selected and data collected via audio recording, as well as demographics and clinical information via questionnaire. Encounters' verbal content was transcribed verbatim, utterances identified, time stamped, and classified according to a coding scheme of fifteen categories. All data was statistically analyzed using SPSSv17. Four dialogue structures: speaker turn, interactivity, turn density and turn duration measurements. From a total of 51 participants, 72.5% were female with a median age of 66 years. The average systolic blood pressure was 140 mmHg, while the diastolic was 78 mmHg. The blood pressure measurement episode lasted for 5:35 min, with an average of 81 utterances. From all utterances registered, 55.3% were produced by the customer. Visits averaged 38 speaker turns, with an interactivity rate of approximately 7 turns per episode minute. For pharmacists, turn duration averaged 7.0 s and turn density 2.1 utterances. The customers' turns comprised a mean of 8.0 s, with 2.4 utterances. Longer episodes were related to more speaker turns and greater customer turn density and duration, but lower dialogue interactivity. The interactivity rate was also lower when the customers' utterances increased. Pharmacists asked more questions (essentially closed ones), while the customers gave more information. No significant associations were observed between elderly/non-elderly and gender in relation to all communication variables. However, an increased number of speaker turns and closed-questions were associated to a higher systolic pressure. It seems that pharmacists tend to control the content of the dialogue, while customers have more influence on the visit duration and interactivity. Specific hypertensive episodes induce

Bernard Tschumi Draws Architecture!

Directory of Open Access Journals (Sweden)

Gevork Hartoonian

2014-08-01

Full Text Available Bernard Tschumi’s delineation prepared for the Museu de Arte Contemporânea provides the starting point for this essay, which discusses the historicity of drawing and highlights the horizontality and the verticality that structure architecture’s contrast with the pictorial realm. Juxtaposing a freehand sketch with the digital image of the same project, Tschumi moves to address the paradox concerning the position of the body and drawing. This drawing also speaks for the reversal in the position of the body brought about by digital reproductivity.The reversal alludes to Tschumi’s theorization of architecture in terms of space and event. These, I will argue, are anticipated in The Manhattan Transcripts (1981 where a set of freehand drawings is used to evoke a filmic mood wherein the image is projected parallel to the spectator’s seated position. The essay goes further, suggesting that the theatricality permeating the present architecture is part of the shift from horizontality to the painterly, and yet the phenomenon is not merely a technical issue. Rather, it alludes to architecture’s dialogical rapport with painting at work since the Renaissance.

Large coal reserves are present in three areas located between 12 and 20 miles southeast of Riverton, Fremont County, central Wyoming. Coal in two of these areas, the Alkali Butte coal field and the Big Sand Draw coal field, is exposed on the surface and has been developed to some extent by underground mining. The Beaver Creek coal field is known only from drill cuttings and cores from wells drilled for oil and gas in the Beaver Creek oil and gas field.These three coal areas can be reached most readily from Riverton, Wyo. State Route 320 crosses Wind River about 1 mile south of Riverton. A few hundred yards south of the river a graveled road branches off the highway and extends south across the Popo Agie River toward Sand Draw oil and gas field. About 8 miles south of the highway along the Sand Draw road, a dirt road bears east and along this road it is about 12 miles to the Bell coal mine in the Alkali Butte coal field. Three miles southeast of the Alkali Butte turn-off, 3 miles of oiled road extends southwest into the Beaver Creek oil and gas field. About 6 miles southeast of the Beaver Creek turn-off, in the valley of Little Sand Draw Creek, a dirt road extends east 1. mile and then southeast 1 mile to the Downey mine in the Big Sand Draw coal field. Location of these coal fields is shown on figure 1 with their relationship to the Wind River basin and other coal fields, place localities, and wells mentioned in this report. The coal in the Alkali Butte coal field is exposed partly on the Wind River Indian Reservation in Tps. 1 and 2 S., R. 6 E., and partly on public land. Coal in the Beaver Creek and Big Sand Draw coal fields is mainly on public land. The region has a semiarid climate with rainfall averaging less than 10 in. per year. When rain does fall the sandy-bottomed stream channels fill rapidly and are frequently impassable for a few hours. Beaver Creek, Big Sand Draw, Little Sand Draw, and Kirby Draw and their smaller tributaries drain the area and flow

Blood and dried blood spot telomere length measurement by qPCR: assay considerations.

Directory of Open Access Journals (Sweden)

DeAnna L Zanet

Full Text Available Measurement of telomere length is crucial for the study of telomere maintenance and its role in molecular pathophysiology of diseases and in aging. Several methods are used to measure telomere length, the choice of which usually depends on the type and size of sample to be assayed, as well as cost and throughput considerations. The goal of this study was to investigate the factors that may influence the reliability of qPCR-based relative telomere length measurements in whole blood. Day to day intra-individual variability, types of blood anticoagulant, sample storage conditions, processing and site of blood draw were investigated. Two qPCR-based methods to measure telomere length (monoplex vs. multiplex were also investigated and showed a strong correlation between them. Freezing and thawing of the blood and storage of the blood at 4°C for up to 4 days did not affect telomere length values. Telomere lengths in dried blood spots were significantly higher than both whole blood and peripheral mononuclear blood cells, and were highly correlated with both. We found that telomere length measurements were significantly higher in dried blood spots collected directly from fingertip prick compared to dried blood spots prepared with anticoagulated whole blood collected from the finger, and non-blotted whole blood taken from both finger and arm venipuncture. This suggests that DNA from cells blotted on paper is not equivalent to that collected from venipuncture whole blood, and caution should be taken when comparing between blood sample types.

Ulk, P.F.

1994-01-01

Safe, efficient operation of waste tank farm facilities is dependent in part upon the availability of accurate, up-to-date plant drawings. Accurate plant drawings are also required in support of facility upgrades and future engineering remediation projects. This supporting document establishes the procedure for performing a visual field verification of engineering drawings, the degree of visual observation being performed and documenting the results. A copy of the drawing attesting to the degree of visual observation will be paginated into the released Engineering Change Notice (ECN) documenting the field verification for future retrieval and reference. All waste tank farm essential and support drawings within the scope of this program will be converted from manual to computer aided drafting (CAD) drawings. A permanent reference to the field verification status will be placed along the right border of the CAD-converted drawing, referencing the revision level, at which the visual verification was performed and documented

Semi-automatic drawings surveying system

International Nuclear Information System (INIS)

Andriamampianina, Lala

1983-01-01

A system for the semi-automatic survey of drawings is presented. Its design has been oriented to the reduction of the stored information required for the drawing reproduction. This equipment consists mainly of a plotter driven by a micro-computer, but the pen of the plotter is replaced by a circular photodiode array. Line drawings are first viewed as a concatenation of vectors, with constant angle between the two vectors, and then divided in arcs of circles and line segments. A dynamic analysis of line intersections with the circular sensor permits to identify starting points and end points in a line, for the purpose of automatically following connected lines in drawing. The advantage of the method described is that precision practically depends only on the plotter performance, the sensor resolution being only considered for the thickness of strokes and the distance between two strokes.

An efficient turn-around will be an important parameter for the integrated luminosity performance at LHC in 2012, when an operation with steady beam parameters and machine configuration will be achieved at the beginning of the run. Improvements of the operational cycle were already put successfully in place after the 2010 experience but additional ways to reduce the time required to setup collisions are possible. In this paper, the 2011 turn-around performance is reviewed and the benefits of the improvements from 2010 are presented. Phases of the operational cycle when further amelioration is possible are discussed and some proposal for a faster turn-around in 2012 are outlined. (authors)

Skepticism and Denial: Drawing a line

Science.gov (United States)

Byrne, J. M.; Brown, M. B.; Peacock, K.

2016-12-01

Climate denialism is distinct from a merely skeptical attitude towards generally accepted views in climate science. But drawing the line between them takes care—there are similarities between skepticism and denial, including a shared reluctance to accept conclusions that nearly all qualified scientists take to be well-justified. Here we will explore both how to draw the line, and how to effectively communicate the differences between denial and skepticism. Identifying which of these two terms best describes someone's attitude turns on whether they reject a generally accepted view based on a `high threshold' for acceptance of conclusions in general, or from a preference that the conclusion in question be false. In most cases, denialism manifests in disregard and mistreatment of evidence, including selective quotation, credulous endorsement of bad sources and incredulous rejection of good sources. Historically, current accepted views became dominant as alternatives were excluded and arguments supporting current views accumulated. The accumulated record of evidence and successful application of those views sets a high bar for proposed alternatives to them. Pure skeptics may refuse to endorse generally accepted views without rejecting or distorting the strong evidence for those views, and typically support policy responses based on the implications of that evidence. But deniers who reject scientific conclusions reject the evidence for those views while endorsing views that a true skeptic would regard as less plausible and well-supported than the accepted views. Thus motivated cognition is the key to defining denial. Pascal's famous argument for belief in God illustrates the problem: even assuming God's existence to be extremely improbable, the expected value of believing is far higher than the expected value of disbelieving. But Pascal's argument undermines its own methodology: without reasons to rely on beliefs as reliable guides to successful action, cost

The objectives of the study were to (1) assess the extent to which interrater reliability of pain drawing location and dispersion scoring methods are similar across pain disciplines in a sample of patients with cancer treatment-induced neuropathic pain ( N = 56) and (2) investigate indicators of validity of the pain drawing in this unique sample. Patients undergoing cancer therapy completed the Brief Pain Inventory Body Map, the MD Anderson Symptom Inventory, and the McGill Pain Questionnaire. Intraclass correlation coefficients among medical and psychology professionals ranged from .93-.99. Correlations between pain drawing score and symptom burden severity ranged from .29-.39; correlations between pain drawing score and symptom burden interference ranged from .28-.34. Patients who endorsed pain in the hands and feet more often described their pain as electric, numb, and shooting than patients without pain in the hands and feet. They also endorsed significantly more descriptors of neuropathic pain. Results suggest a similar understanding among members of a multidisciplinary pain team as to the location and dispersion of pain as represented by patients' pain drawings. In addition, pain drawing scores were related to symptom burden severity and interference and descriptors of neuropathic pain in expected ways.

The description of protein 3D structure usually focuses on the repetitive local folds (alpha-helices and beta-sheets). The remaining class, sometimes called unordered region, has often been considered as random (one also calls it ‘random coil'). However, some interesting local folds are also highly recurrent and definitely more structured than a real random region. One of such particularly interesting motif is tight turn; this latter is characterized by few residues (3 to 5) and by the revers...

Tuberculosis (TB) is the leading cause of mortality among people living with HIV (PLHIV), despite the availability of effective preventive therapy. The TEKO trial is assessing the impact of using a blood test, Quantiferon-TB Gold In-Tube Test (QGIT), to screen for latent TB compared to the Tuberculin Screening Test (TST) among PLHIV in South Africa. Fifty-six qualitative interviews were conducted with PLHIV and clinical providers participating in the TEKO trial. We explored TB screening, diagnosis, and treatment guidelines and processes and the use of the QGIT to screen for latent TB infection at the time of CD4 blood draw. Thematic content analysis was conducted. Considerable variability in TB screening procedures was documented due to lack of personnel and clarity regarding current national TB guidelines for PLHIV. Few clinics had started using the TST per national guidelines and many patients had never heard of isoniazid preventive therapy (IPT). Nearly all participants supported the idea of latent TB screening using routine blood drawn for CD4 counts. Findings indicate that screening for latent TB infection using QGIT from blood drawn for CD4 counts among PLHIV is an acceptable approach to increase latent TB detection given the challenges associated with ensuring systematic latent TB screening in overburdened public clinics. The results presented here were from formative research related to the TEKO trial (Identifier NCT02119130 , registered 10 April 2014).

Novel concept for measurement of global blank draw-in when deep drawing outer skin automotive components

Science.gov (United States)

Kraft, M.; Bürgel, U.

2017-09-01

Modern press shops in the automotive industry have to deal with many challenges. One challenge is to achieve a consistent part quality. In order to reach this target, modern press systems and tools are equipped with several types of sensors. For example, there are sensors to measure characteristic values of blanks or sensors to measure the temperature in the tools. Often several sensors are used simultaneously. A significant parameter for determining the quality of draw panels is the draw-in amount. Previously, it was only possible to measure selective points of the draw-in amount due to sensors in the tools. All the known sensors have disadvantages, for example, they are exposed to wearing or susceptible to contamination. In this paper, a sensor system will be introduced that allows the measurement of the global draw-in amount of a drawn panel. Here, the draw-in amount is not measured in the draw die, it is measured during the transportation of the part to the following operation. Within the short transport time the part can be fully covered by an optical system. This leads to a multitude of advantages compared with previously known systems. For example, it is no longer necessary to equip every tool with sensor technology to measure the draw-in amount. Now it is sufficient to equip every press line with a single system to measure the draw-in. This fact leads not only to lower costs, it also simplifies the tool design. In addition, the risk of contamination of the sensor system is greatly reduced. The paper will also introduce an actuator that was built to locally vary the blankholder forces for a sheet metal forming process. Furthermore, an FEM model is presented that allows the determination of the effective range of these actuators. With the knowledge from the FEM simulation, an approach for an open loop control is presented. With this approach, the press shops at Opel are developing a control procedure in order to influence the stamping process positively.

Blood collection through intravenous (IV) catheters is a common practice at emergency departments (EDs). This technique is associated with higher in vitro hemolysis rates and may even be amplified by the use of vacuum collection tubes. Our aim was to investigate the association of five different vacuum tubes with hemolysis rates in comparison to an aspiration system under real-life conditions and to propose an equation to estimate the amount of hemolysis, depending on the vacuum collection tube type. We retrospectively evaluated hemolysis data of plasma samples from our ED, where blood is drawn through IV catheters. Over the past 5 years, we compared 19,001 hemolysis index values amongst each other and against the respective vacuum pressure (Pv) of the collection tubes, which were used within the six observational periods. The highest hemolysis rates were associated with full-draw evacuated tubes. Significantly reduced hemolysis was observed for two kinds of partial-draw tubes. The hemolysis rate of one partial-draw blood collection tube was comparable to those of the aspiration system. Regression analysis of Pv and mean free hemoglobin (fHb) values yielded the formula fHb (g/L)=0.0082*Pv2-0.1143*Pv+ 0.5314 with an R2 of 0.99. If IV catheters are used for blood collection, hemolysis rates directly correlate with the vacuum within the tubes and can be estimated by the proposed formula. By the use of partial-draw vacuum blood collection tubes, hemolysis rates in IV catheter collections can be reduced to levels comparable with collections performed by aspiration systems.

Busby, Helen; Kent, Julie; Farrell, Anne-Maree

2014-01-01

The clinical use of blood has a long history, but its apparent stability belies the complexity of contemporary practices in this field. In this article, we explore how the production, supply and deployment of blood products are socially mediated, drawing on theoretical perspectives from recent work on 'tissue economies'. We highlight the ways in which safety threats in the form of infections that might be transmitted through blood and plasma impact on this tissue economy and how these have led to a revaluation of donor bodies and restructuring of blood economies. Specifically, we consider these themes in relation to the management of recent threats to blood safety in the United Kingdom. We show that the tension between securing the supply of blood and its products and ensuring its safety may give rise to ethical concerns and reshape relations between donor and recipient bodies.

This paper introduces the digital lock-in detection theory and discusses its feasibility to obtain the damping rate in turn-by-turn measurement systems. Numerical simulations of this method were carried out with Matlab. Then principle presenting beam experiments were conducted on the Hefei Light Source (HLS) storage ring. The measured beta oscillation growth time is about 0.26 ms and the damping time is about 1.2 ms. Simulation and experimental results show that, the digital lock-in detection method is effective in damping rate measurement in turn-by-turn measurement systems. (authors)

How children use drawing to regulate their emotions.

Drake, Jennifer E; Winner, Ellen

2013-01-01

We examined two ways in which drawing may function to elevate mood in children-venting (expressing negative feelings) and distraction (expressing something unrelated to the negative feelings). We examined the effectiveness of drawing as an emotion regulator when drawing is used to vent versus distract (Study 1) and tested whether the effects found are specific to the activity of creating one's own drawing or generalisable to a drawing activity in which children had to copy another's drawing (Study 2). To induce a negative mood, we asked children to think of a disappointing event. Mood was assessed before and after the assigned activity. In both studies, mood improved significantly more in the distract than in the vent or copy condition. Study 1 demonstrates that drawing improves mood in children via distraction and not via venting. Study 2 demonstrates that this effect is specific to a drawing task in which an image is freely constructed. When a copying task is used, the effect disappears.

2016-10-01

Turning difficulty is common in people with Parkinson disease (PD). The clock-turn strategy is a cognitive movement strategy to improve turning performance in people with PD despite its effects are unverified. Therefore, this study aimed to investigate the effects of the clock-turn strategy on the pattern of turning steps, turning performance, and freezing of gait during a narrow turning, and how these effects were influenced by concurrent performance of a cognitive task (dual task). Twenty-five people with PD were randomly assigned to the clock-turn or usual-turn group. Participants performed the Timed Up and Go test with and without concurrent cognitive task during the medication OFF period. The clock-turn group performed the Timed Up and Go test using the clock-turn strategy, whereas participants in the usual-turn group performed in their usual manner. Measurements were taken during the 180° turn of the Timed Up and Go test. The pattern of turning steps was evaluated by step time variability and step time asymmetry. Turning performance was evaluated by turning time and number of turning steps. The number and duration of freezing of gait were calculated by video review. The clock-turn group had lower step time variability and step time asymmetry than the usual-turn group. Furthermore, the clock-turn group turned faster with fewer freezing of gait episodes than the usual-turn group. Dual task increased the step time variability and step time asymmetry in both groups but did not affect turning performance and freezing severity. The clock-turn strategy reduces turning time and freezing of gait during turning, probably by lowering step time variability and asymmetry. Dual task compromises the effects of the clock-turn strategy, suggesting a competition for attentional resources.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, http://links.lww.com/JNPT/A141).

Drawing conclusions: a re-examination of empirical and conceptual bases for psychological evaluation of children from their drawings.

Science.gov (United States)

Thomas, G V; Jolley, R P

1998-05-01

Although consideration of children's art work (usually drawings) in clinical investigations of children referred to psychologists is fairly common, there is little evidence for the reliability and validity of such assessments. We consider a variety of possible mechanisms which could operate to influence the characteristics of children's drawings, and review the evidence that such mechanisms operate to allow meaningful psychological evaluations of children from their drawings. The problem for making a reliable interpretation of the significance of a drawing is that a given feature could plausibly support several very different interpretations, depending which of many possible processes was active or dominant in the production of the drawing. Evidence from studies of clinical populations and experimental studies with non-selected samples are reviewed in the light of these possibilities. The review indicates that drawings are inaccurate and unreliable as personality or state assessments but can be influenced by children's emotional attitudes towards the topics depicted. The form of that expression, however, may be personal and idiosyncratic. Analogue studies of these effects undertaken with non-clinical samples under controlled conditions have produced mixed results. At best the reported effects are small. Children's drawings on their own are too complexly determined and inherently ambiguous to be reliable sole indicators of the emotional experiences of the children who drew them. Further research is needed to establish the extent to which such drawings can usefully facilitate assessment of children by other means or provide useful support as one of several converging lines of evidence.

This study used student-generated drawings to explore student knowledge in a HA&P course. The drawing tasks in this study focused on chemical synapses between neurons, an abstract concept in HA&P. Using two preinstruction drawing tasks, students were asked to depict synaptic transmission and summation. In response to the first drawing task, 20% of students ( n = 352) created accurate representations of neuron anatomy. The remaining students created drawings suggesting an inaccurate or incomplete understanding of synaptic transmission. Of the 208 inaccurate student-generated drawings, 21% depicted the neurons as touching. When asked to illustrate summation, only 10 students (roughly 4%) were able to produce an accurate drawing. Overall, students were more successful at drawing anatomy (synapse) than physiology (summation) before formal instruction. The common errors observed in student-generated drawings indicate students do not enter the classroom as blank slates. The error of "touching" neurons in a chemical synapse suggests that students may be using intuitive or experiential knowledge when reasoning about physiological concepts. These results 1 ) support the utility of drawing tasks as a tool to reveal student content knowledge about neuroanatomy and neurophysiology; and 2 ) suggest students enter the classroom with better knowledge of anatomy than physiology. Collectively, the findings from this study inform both practitioners and researchers about the prevalence and nature of student difficulties in HA&P, while also demonstrating the utility of drawing in revealing student knowledge.

The genesis of errors in drawing.

Science.gov (United States)

Chamberlain, Rebecca; Wagemans, Johan

2016-06-01

The difficulty adults find in drawing objects or scenes from real life is puzzling, assuming that there are few gross individual differences in the phenomenology of visual scenes and in fine motor control in the neurologically healthy population. A review of research concerning the perceptual, motoric and memorial correlates of drawing ability was conducted in order to understand why most adults err when trying to produce faithful representations of objects and scenes. The findings reveal that accurate perception of the subject and of the drawing is at the heart of drawing proficiency, although not to the extent that drawing skill elicits fundamental changes in visual perception. Instead, the decisive role of representational decisions reveals the importance of appropriate segmentation of the visual scene and of the influence of pictorial schemas. This leads to the conclusion that domain-specific, flexible, top-down control of visual attention plays a critical role in development of skill in visual art and may also be a window into creative thinking.

Forrest, M; Thomas, G V

1991-11-01

Bereaved and non-bereaved children made drawings of a person, themselves, their family, and a topic of their choice; the drawings were then analysed to investigate whether the experience of bereavement was expressed in drawing in any reliable way. Bereaved children were no more likely than non-bereaved children to include indicators of emotional disturbance in their human figure drawings. Bereaved children, however, were reliably more likely than non-bereaved children to include themselves in a drawing of their family.

Accessible engineering drawings for visually impaired machine operators.

Science.gov (United States)

Ramteke, Deepak; Kansal, Gayatri; Madhab, Benu

2014-01-01

An engineering drawing provides manufacturing information to a machine operator. An operator plans and executes machining operations based on this information. A visually impaired (VI) operator does not have direct access to the drawings. Drawing information is provided to them verbally or by using sample parts. Both methods have limitations that affect the quality of output. Use of engineering drawings is a standard practice for every industry; this hampers employment of a VI operator. Accessible engineering drawings are required to increase both independence, as well as, employability of VI operators. Today, Computer Aided Design (CAD) software is used for making engineering drawings, which are saved in CAD files. Required information is extracted from the CAD files and converted into Braille or voice. The authors of this article propose a method to make engineering drawings information directly accessible to a VI operator.

Additive Manufacturing of Patient-Customizable Scaffolds for Tubular Tissues Using the Melt-Drawing Method.

Science.gov (United States)

Tan, Yu Jun; Tan, Xipeng; Yeong, Wai Yee; Tor, Shu Beng

2016-11-03

Polymeric fibrous scaffolds for guiding cell growth are designed to be potentially used for the tissue engineering (TE) of tubular organs including esophagi, blood vessels, tracheas, etc. Tubular scaffolds were fabricated via melt-drawing of highly elastic poly(l-lactide-co-ε-caprolactone) (PLC) fibers layer-by-layer on a cylindrical mandrel. The diameter and length of the scaffolds are customizable via 3D printing of the mandrel. Thickness of the scaffolds was varied by changing the number of layers of the melt-drawing process. The morphology and tensile properties of the PLC fibers were investigated. The fibers were highly aligned with a uniform diameter. Their diameters and tensile properties were tunable by varying the melt-drawing speeds. These tailorable topographies and tensile properties show that the additive-based scaffold fabrication technique is customizable at the micro- and macro-scale for different tubular tissues. The merits of these scaffolds in TE were further shown by the finding that myoblast and fibroblast cells seeded onto the scaffolds in vitro showed appropriate cell proliferation and distribution. Human mesenchymal stem cells (hMSCs) differentiated to smooth muscle lineage on the microfibrous scaffolds in the absence of soluble induction factors, showing cellular shape modulation and scaffold elasticity may encourage the myogenic differentiation of stem cells.

Turn-by-Turn and Bunch-by-Bunch Transverse Profiles of a Single Bunch in a Full Ring

International Nuclear Information System (INIS)

Kraus, R.; Fisher, A.S.

2005-01-01

The apparatus described in this paper can image the evolution of the transverse profile of a single bunch, isolated from a full PEP-II ring of 1500 bunches. Using this apparatus there are two methods of single bunch imaging; bunch-by-bunch beam profiling can image every bunch in the ring a single bunch at a time with the images of sequential bunches being in order, allowing one to see variations in beam size along a train. Turn-by-turn beam profiling images a single bunch on each successive turn it makes around the ring. This method will be useful in determining the effect that an injected bunch has on a stable bunch as the oscillations of the injected bunch damp out. Turn-by-turn imaging of the synchrotron light uses a system of lenses and mirrors to image many turns of both the major and minor axis of a single bunch across the photocathode of a gateable camera. The bunch-by-bunch method is simpler: because of a focusing mirror used in porting the light from the ring, the synchrotron light from the orbiting electrons becomes an image at a certain distance from the mirror; and since the camera does not use a lens, the photocathode is set exactly at this image distance. Bunch-by-bunch profiling has shown that in the Low Energy Ring (LER) horizontal bunch size decreases along a train. Turn-by-turn profiling has been able to image 100 turns of a single bunch on one exposure of the camera. The turn-by-turn setup has also been able to image 50 turns of the minor axis showing part of the damping process of an oscillating injected charge during a LER fill. The goal is to image the damping of oscillations of injected charge for 100 turns of both the major and minor axis throughout the damping process during trickle injection. With some changes to the apparatus this goal is within reach and will make turn-by-turn imaging a very useful tool in beam diagnostics

[Blood donation in urban areas].

Science.gov (United States)

Charpentier, F

2013-05-01

Medical and technical developments increase the difficulty to provide sufficient safe blood for all patients in developed countries and their sociodemographic and societal changes. Sufficient national blood supply remains a reached, however still actual, challenge. Tomorrow is prepared today: the management of blood donation programs both in line with these developments and with social marketing strategies is one of the keys to success. If the main components of this organization are well known (mobile blood drives in various appropriate environments, and permanent blood donation centers) their proportions in the whole process must evolve and their contents require adaptations, especially for whole blood donation in urban areas. We have to focus on the people's way of life changes related to increasing urbanization of the society and prominent position taken by very large cities. This requires targeting several goals: to draw the attention of the potential blood-giving candidate, to get into position to collect him when he will decide it, to give meaning and recognition to his "sacrifice" (give time rather than donate blood) and to give him desire and opportunity to come back and donate one more time. In this strategy, permanent blood centers in urban areas have significant potential for whole blood collection, highlighted by the decrease of apheresis technology requirements. This potential requires profound changes in their location, conception and organization. The concept of Maison Du Don (MDD) reflects these changes. Copyright © 2013. Published by Elsevier SAS.

Fabricating tungsten crucibles by drawing and extrusion spinning

International Nuclear Information System (INIS)

Edstrom, C.M.

1981-01-01

The fabrication of seamless tungsten crucibles 127-mm ID x 265-mm high x 6.25-mm wall thickness (5 in. x 10 1/2 in. x 1/4 in.) involved three drawing operations and extrusion spinning. The success of the drawing operations came from a combination of low draw reduction percentage, generous draw radii, large punch-to-die clearance, and attention to drawing temperature. The extrusion spinning success related to good drawn-cup-to-spinning-mandrel fit prior to making the extrusion passes, removal of stress risers in the part prior to spinning, and special attention to part and mandrel temperature

Beam Optics Measurements Through Turn by Turn Beam Position Data in the SLS

CERN Document Server

Zisopoulos, P; Streun, A; Ziemann, v

2013-01-01

Refined Fourier analysis of turn-by-turn (TBT) transverse position data measurements can be used for determining several beam properties of a ring, such as transverse tunes, optics functions, phases, chromatic properties and coupling. In particular, the Numerical Analysis of Fundamental Frequencies (NAFF) algorithm is used to analyse TBT data from the Swiss Light Source (SLS) storage ring in order to estimate on and off-momentum beam characteristics. Of particular interest is the potential of using the full position information within one turn in order to measure beam optics properties.

Realistic page-turning of electronic books

Fan, Chaoran; Li, Haisheng; Bai, Yannan

2014-01-01

The booming electronic books (e-books), as an extension to the paper book, are popular with readers. Recently, many efforts are put into the realistic page-turning simulation o f e-book to improve its reading experience. This paper presents a new 3D page-turning simulation approach, which employs piecewise time-dependent cylindrical surfaces to describe the turning page and constructs smooth transition method between time-dependent cylinders. The page-turning animation is produced by sequentially mapping the turning page into the cylinders with different radii and positions. Compared to the previous approaches, our method is able to imitate various effects efficiently and obtains more natural animation of turning page.

The influence of stimulus format on drawing--a functional imaging study of decision making in portrait drawing.

Science.gov (United States)

Miall, R C; Nam, Se-Ho; Tchalenko, J

2014-11-15

To copy a natural visual image as a line drawing, visual identification and extraction of features in the image must be guided by top-down decisions, and is usually influenced by prior knowledge. In parallel with other behavioral studies testing the relationship between eye and hand movements when drawing, we report here a functional brain imaging study in which we compared drawing of faces and abstract objects: the former can be strongly guided by prior knowledge, the latter less so. To manipulate the difficulty in extracting features to be drawn, each original image was presented in four formats including high contrast line drawings and silhouettes, and as high and low contrast photographic images. We confirmed the detailed eye-hand interaction measures reported in our other behavioral studies by using in-scanner eye-tracking and recording of pen movements with a touch screen. We also show that the brain activation pattern reflects the changes in presentation formats. In particular, by identifying the ventral and lateral occipital areas that were more highly activated during drawing of faces than abstract objects, we found a systematic increase in differential activation for the face-drawing condition, as the presentation format made the decisions more challenging. This study therefore supports theoretical models of how prior knowledge may influence perception in untrained participants, and lead to experience-driven perceptual modulation by trained artists.

Full Text Available The article focuses on the optimization of the earlier discussed computer method of obtaining new forms of polyhedra based on projective geometry drawings (trace Diagrams.While working on getting new multifaceted forms by projective geometry methods based on the well-known models of polyhedra on the first stage of the work it is required to calculate the parameters of projective geometry drawings, and then to build them. This is an often used apparatus of analytical geometry. According to it, at first the parameters of the polyhedron (core system of planes are calculated, then we obtain the equation of the plane of the face of the polyhedron, and finally we obtain the equations of lines the next plane faces on the selected curve plane. At each stage of application such a method requires the use of the algorithms of floating point arithmetic, on the one hand, leads to some loss of accuracy of the results and, on the other hand, the large amount of computer time to perform these operations in comparison with integer arithmetic operations.The proposed method is based on the laws existing between the lines that make up the drawing - the known configurations of projective geometry (complete quadrilaterals, configuration of Desargues, Pappus et al..The authors discussed in detail the analysis procedure of projective geometry drawing and the presence of full quadrilaterals, Desargues and Pappus configurations in it.Since the composition of these configurations is invariant with respect to projective change of the original nucleus, knowing them, you can avoid the calculations when solving the equations for finding direct projective geometry drawing analytically, getting them on the basis of belonging to a particular configuration. So you can get a definite advantage in accuracy of the results, and in the cost of computer time. Finding these basic configurations significantly enriches the set of methods and the use of projective geometry drawings.

Hummingbirds control turning velocity using body orientation and turning radius using asymmetrical wingbeat kinematics.

Science.gov (United States)

Read, Tyson J G; Segre, Paolo S; Middleton, Kevin M; Altshuler, Douglas L

2016-03-01

Turning in flight requires reorientation of force, which birds, bats and insects accomplish either by shifting body position and total force in concert or by using left-right asymmetries in wingbeat kinematics. Although both mechanisms have been observed in multiple species, it is currently unknown how each is used to control changes in trajectory. We addressed this problem by measuring body and wingbeat kinematics as hummingbirds tracked a revolving feeder, and estimating aerodynamic forces using a quasi-steady model. During arcing turns, hummingbirds symmetrically banked the stroke plane of both wings, and the body, into turns, supporting a body-dependent mechanism. However, several wingbeat asymmetries were present during turning, including a higher and flatter outer wingtip path and a lower more deviated inner wingtip path. A quasi-steady analysis of arcing turns performed with different trajectories revealed that changes in radius were associated with asymmetrical kinematics and forces, and changes in velocity were associated with symmetrical kinematics and forces. Collectively, our results indicate that both body-dependent and -independent force orientation mechanisms are available to hummingbirds, and that these kinematic strategies are used to meet the separate aerodynamic challenges posed by changes in velocity and turning radius. © 2016 The Author(s).

Cognitive flexibility in drawings of bilingual children.

2010-01-01

A. Karmiloff-Smith's (1990) task of drawing a nonexistent object is considered to be a measure of cognitive flexibility. The notion of earlier emergence of cognitive flexibility in bilingual children motivated the current researchers to request 4- and 5-year-old English-Hebrew and Arabic-Hebrew bilingual children and their monolingual peers to draw a flower and a house that do not exist (N=80). Bilinguals exhibited a significantly higher rate of interrepresentational flexibility in their drawings (e.g., "a giraffe flower,"a chair-house," found in 28 of 54 drawings), whereas the level of complex intrarepresentational change was similar across groups. Interrepresentational drawings were previously reported only for children older than 7 years. The specific mechanisms by which bilinguals' language experience may lead to interrepresentational flexibility are discussed. © 2010 The Authors.

Cold-drawing sheet molybdenum at room temperature

International Nuclear Information System (INIS)

Shepherd, L.W.

1975-11-01

When sheet molybdenum is cold-drawn and annealed, the microstructure recrystallizes, and may cause the metal to become brittle, with loss of ductility and strength. Ten to twenty percent recrystallization can occur to destroy optimum drawing quality of the metal. A recrystallization of 4 to 5 percent is ideal. It is shown that special tooling and controlled annealing can hold recrystallization to optimum levels. Special tooling includes an automatic cycling press that closely controls the rate of draw and gives maximum pressure. A draw sleeve of high carbon steel is used. The draw sleeve can be highly polished to minimize friction and provides an intensifying effect of the ram force over the entire part. Four draw steps are used, with each step followed by an annealing at 925 0 C for 20 minutes. Results of recrystallization analysis show that the ideal five percent recrystallization is achieved with this process

Hospitalized children can have various fantasies about hospital, health staff, and related tools and equipment. They need to develop new coping strategies for compliance with hospitalization.This study aimed to investigate the perception of nurses by children with acute and chronic illness through their drawings. The study was carried out using a descriptive research model. "Nurses through the eyes of sick children data collection form" was used in data collection procedure. The instruction "draw a picture of a nurse, please" was used to get the children to draw a picture. The majority of the children portrayed nurses as a smiling face. The children with chronic diseases featured nurses more in their drawings and they mentioned more nurse duties. The most important sign of the progression of nursing is that the mentioning of the modern roles of nursing by the children in their drawings and expressions. As children are influenced by their emotions, thoughts, observations, and experiences while drawing pictures, nurses can determine their thoughts about the disease, hospitals, physicians, and nurses by having sick children draw pictures.

Professionals examine various aspects of girls' and boys' drawings as a way of understanding their intelligence, personality and emotional state. However, the extent to which such measures could be universally generalised or attributed to a specific cultural norm is still a debatable issue. In the present study five key features of children's drawings namely: the size (height) of the drawings, profile or full face, figure in action or static, shaded or non-shaded and the nature of additional details were examined from a cross-cultural perspective, and by providing a topic (football) for which children's drawing of a human figure could provide opportunities for the latter indices to manifest and flourish. Children from three countries; England, Iran and Brazil, representing three continents took part in this study. The participants were asked to draw a football player from their own country and from the other participating countries. The results showed that Brazilian children differ from Iranian and English children by drawing significantly smaller figures and putting more football action in the drawings. Shading of the figure drawn was more prevalent amongst English children. Such findings have implications for the interpretation of key aspects of children's drawings in educational, clinical and therapeutic settings and from a universal vs. culturally-specific viewpoint.

Since the images have been put up, the viewers have enjoyed the contrast between the "before" pictures of vibrant Albert Einsteins to the "after" pictures of casual people sitting in an office. The large room in the Globe has been transformed from a hollow shell int...

Ethnic differences in the Goodenough-Harris draw-a-man and draw-a-woman tests.

Dugdale, A E; Chen, S T

1979-11-01

The draw-a-man (DAM) and draw-a-woman (DAW) tests were given to 307 schoolchildren in Petaling Jaya, Malaysia. The children were ethnically Malay, Chinese, or Indian (Tamil), and all came from lower socioeconomic groups. The standard scores of the Chinese children averaged 118 in the DAM and 112 in the DAW tests. These scores were significantly better than the American standards. Malay children scored significantly lower than Chinese, and Tamil children scored lower again. The nutritional status of the children had no influence on the scores. Chinese and Tamil children scored better in the DAM than the DAW, while in Malay boys the reverse was true. Malay children tended to emphasise clothing in the DAM, but Chinese and Tamil children scored better on items relating to facial features and body proportions. The Goodenough-Harris draw-a-person tests are obviously not culture-free, but the causes of ethnic differences have not been elucidated.

Determinants of pulmonary blood flow distribution.

Science.gov (United States)

Glenny, Robb W; Robertson, H Thomas

2011-01-01

The primary function of the pulmonary circulation is to deliver blood to the alveolar capillaries to exchange gases. Distributing blood over a vast surface area facilitates gas exchange, yet the pulmonary vascular tree must be constrained to fit within the thoracic cavity. In addition, pressures must remain low within the circulatory system to protect the thin alveolar capillary membranes that allow efficient gas exchange. The pulmonary circulation is engineered for these unique requirements and in turn these special attributes affect the spatial distribution of blood flow. As the largest organ in the body, the physical characteristics of the lung vary regionally, influencing the spatial distribution on large-, moderate-, and small-scale levels. © 2011 American Physiological Society.

Artistic drawing as a mnemonic device

Science.gov (United States)

Baker Christensen, Leslie

Despite art-based learning being widely used, existing data are primarily qualitative, and most research has not isolated particular variables such as memory for empirical study. The few experiments that have been conducted demonstrated that drawing improves free recall of unpaired words, and retention improves after lessons integrated with drawing, drama, and narrative exercises. To help fill the gap in the current literature, the present study compared the effectiveness of encoding and the rate of memory decay between a drawing mnemonic and note taking on a paired associates task. Using a within-subjects experimental design, participants were presented with word pairs and asked to complete either a drawing mnemonic (DM) or note taking (NT) to assist memorization. Participants were tested immediately after the word pair presentation and after a 20-minute delay. Results supported the hypothesis that the DM condition would produce superior encoding, as evidenced by greater retention on the immediate test. However, no memory decay was observed in the experiment, and therefore results on the delayed test were inconclusive. In fact, scores for the NT condition improved over time whereas the scores for the DM condition did not, which might imply that note taking results in a different consolidation process than drawing. Findings from this study suggested that arts integration can be an effective method to support memory for learned information. Future studies that examine the effect of rehearsal and the long-term effectiveness of a drawing mnemonic are warranted.

2013-01-01

The performance of the CERN Proton Synchrotron (PS) has been constantly increasing over the years both in terms of beam parameters (intensity and brightness) and beam manipulations (transverse and longitudinal splitting). This implies a very good knowledge of the linear and non-linear model of the ring. In this paper we report on a detailed campaign of beam measurements based on turn-by-turn orbit data aimed at measuring the optics in several conditions as well as the resonance driving terms.

Drawings vs. narratives: drawing as a tool to encourage verbalization in children whose fathers are drug abusers.

Science.gov (United States)

Lev-Wiesel, Rachel; Liraz, Revital

2007-01-01

The study aimed to examine the extent to which the use of drawing prior to narrative description increases the richness of the narrative given by children who are exposed to a succession of negative life events. The sample consisted of study and comparison groups (60 children: 27 boys, 33 girls), ranging in age from 9 to 14, whose fathers were addicted to drugs. The study group was asked to first 'draw your life in the shadow of your father's addiction to drugs', then verbally describes 'your life under the shadow of an addicted father'; the comparison group was asked only the latter. Following evaluation of drawings and narratives by two judges, analysis of variance between the groups' narratives revealed that when children were first asked to draw, their narratives were more detailed and more revealing of emotions compared to children who were asked only to verbally describe their lives, whereas expressions of resistance and splitting were more apparent in the comparison group.

NetTurnP--neural network prediction of beta-turns by use of evolutionary information and predicted protein sequence features.

Directory of Open Access Journals (Sweden)

Bent Petersen

Full Text Available UNLABELLED: β-turns are the most common type of non-repetitive structures, and constitute on average 25% of the amino acids in proteins. The formation of β-turns plays an important role in protein folding, protein stability and molecular recognition processes. In this work we present the neural network method NetTurnP, for prediction of two-class β-turns and prediction of the individual β-turn types, by use of evolutionary information and predicted protein sequence features. It has been evaluated against a commonly used dataset BT426, and achieves a Matthews correlation coefficient of 0.50, which is the highest reported performance on a two-class prediction of β-turn and not-β-turn. Furthermore NetTurnP shows improved performance on some of the specific β-turn types. In the present work, neural network methods have been trained to predict β-turn or not and individual β-turn types from the primary amino acid sequence. The individual β-turn types I, I', II, II', VIII, VIa1, VIa2, VIba and IV have been predicted based on classifications by PROMOTIF, and the two-class prediction of β-turn or not is a superset comprised of all β-turn types. The performance is evaluated using a golden set of non-homologous sequences known as BT426. Our two-class prediction method achieves a performance of: MCC=0.50, Qtotal=82.1%, sensitivity=75.6%, PPV=68.8% and AUC=0.864. We have compared our performance to eleven other prediction methods that obtain Matthews correlation coefficients in the range of 0.17-0.47. For the type specific β-turn predictions, only type I and II can be predicted with reasonable Matthews correlation coefficients, where we obtain performance values of 0.36 and 0.31, respectively. CONCLUSION: The NetTurnP method has been implemented as a webserver, which is freely available at http://www.cbs.dtu.dk/services/NetTurnP/. NetTurnP is the only available webserver that allows submission of multiple sequences.

Listen to them draw: screening children in primary care through the use of human figure drawings.

Science.gov (United States)

Tielsch, Anna H; Allen, Patricia Jackson

2005-01-01

This literature review focuses on the Human Figure Drawing (HFD) methods put forth by Elizabeth Koppitz as a screening instrument. Children's drawings have potential as a mental health screening aide for health care practitioners in the primary care setting. This paper focuses on self-portrait drawings as a screening technique for emotional well-being, anxiety, and depression in school-aged children (6-12 years old). Using Koppitz's emotional indicators checklist for mental health, practitioners can use the child's HFD as a quick screening tool. Although the HFD is not diagnostic and can not be used as the sole indicator for anxiety or depression, two or more emotional indicators may signal to the clinician that further psychiatric assessment and referral is needed.

Drawing-Based Procedural Modeling of Chinese Architectures.

Science.gov (United States)

Fei Hou; Yue Qi; Hong Qin

2012-01-01

This paper presents a novel modeling framework to build 3D models of Chinese architectures from elevation drawing. Our algorithm integrates the capability of automatic drawing recognition with powerful procedural modeling to extract production rules from elevation drawing. First, different from the previous symbol-based floor plan recognition, based on the novel concept of repetitive pattern trees, small horizontal repetitive regions of the elevation drawing are clustered in a bottom-up manner to form architectural components with maximum repetition, which collectively serve as building blocks for 3D model generation. Second, to discover the global architectural structure and its components' interdependencies, the components are structured into a shape tree in a top-down subdivision manner and recognized hierarchically at each level of the shape tree based on Markov Random Fields (MRFs). Third, shape grammar rules can be derived to construct 3D semantic model and its possible variations with the help of a 3D component repository. The salient contribution lies in the novel integration of procedural modeling with elevation drawing, with a unique application to Chinese architectures.

The Literature Curriculum in Russia Cultural Nationalism vs. The Cultural Turn

Directory of Open Access Journals (Sweden)

Karin Sarsenov

2010-11-01

Full Text Available In Western educational systems, the question “Why study literature in school?” has been raised in connection with the theoretical development often summarized as “the cultural turn.” The author strives to contribute to this discussion by examining the development of educational discourse in Russia. During the Soviet period, literature was – together with history – the subject most heavily influenced by the dogmas of Soviet state ideology. As such, literature enjoyed great prestige and was a compulsory and separate subject from the fifth to the eleventh school years. Since 1991, the educational system has undergone radical reform, but the number of hours devoted to literature has not changed significantly. This would suggest that literature still is perceived as an important means of incorporating children into the national and political community. The target of this study is to identify authorities’ specific aims in devoting so much time to literature in school, as well as to elucidate in what way literature is to achieve these aims. Russian guidelines for the development of literature curricula published in the years 1991–2010 are examined to see just how literature is legitimated as a secondary school subject. Based on this material, the author draws conclusions about the rhetorical practices and ideological development of curricular discourse, its relationship to Soviet educational thought and the extent to which the cultural turn has influenced this sphere.

Beta-and gamma-turns in proteins revisited: a new set of amino acid turn-type dependent positional preferences and potentials.

Science.gov (United States)

Guruprasad, K; Rajkumar, S

2000-06-01

The number of beta-turns in a representative set of 426 protein three-dimensional crystal structures selected from the recent Protein Data Bank has nearly doubled and the number of gamma-turns in a representative set of 320 proteins has increased over seven times since the previous analysis. Beta-turns (7153) and gamma-turns (911) extracted from these proteins were used to derive a revised set of type-dependent amino acid positional preferences and potentials. Compared with previous results, the preference for proline, methionine and tryptophan has increased and the preference for glutamine, valine, glutamic acid and alanine has decreased for beta-turns. Certain new amino acid preferences were observed for both turn types and individual amino acids showed turn-type dependent positional preferences. The rationale for new amino acid preferences are discussed in the light of hydrogen bonds and other interactions involving the turns. Where main-chain hydrogen bonds of the type NH(i + 3) --> CO(i) were not observed for some beta-turns, other main-chain hydrogen bonds or solvent interactions were observed that possibly stabilize such beta-turns. A number of unexpected isolated beta-turns with proline at i + 2 position were also observed. The NH(i + 2) --> CO(i) hydrogen bond was observed for almost all gamma-turns. Nearly 20% classic gamma-turns and 43% inverse gamma-turns are isolated turns.

Impact of manual preference on directionality in children's drawings.

Science.gov (United States)

Picard, Delphine

2011-01-01

The effects of handedness on directionality in drawing are already well documented in the literature, at least as far as adults are concerned. The present study investigates the impact of manual preference on directionality as seen in the drawing product and drawing process, from a developmental point of view. A total of 120 children aged 5 to 9, both right and left-handed drawers, volunteered for the study. Children were asked to draw twice from memory a set of six common objects. Results indicate that directionality in drawing product varies significantly according to manual preference in the 9-year-old children, but not in the younger age groups. The concomitant increase between 7 and 9 years of age in the use of preferred stroke directions and the impact of manual preference in the drawing process suggests that biomechanical factors might play an important role in behavioural asymmetries in drawing.

Piperno, Francesca; Di Biasi, Stefania; Levi, Gabriel

2007-09-01

The aim of this study is to analyse the family drawings of two groups of physically and/or sexually abused children as compared to the drawings of non-abused children of a matched control group. The drawings by 12 physically abused, 12 sexually abused and 12 non-abused children, all aged between 5 years-old and 10 years-old, were assessed and compared. Family drawings were analysed using a specific Screening Inventory (FDI-Family Drawing Inventory). This Inventory takes into consideration such qualitative and quantitative variables as the quality of drawing, the children's perception of their family members and their own perception of themselves within the family system. The results have shown significant differences between the abused minors and the control group. Abused children are more likely to draw distorted bodies, the human figure is usually represented devoid of details, their drawings generally show clear signals of trauma and the majority of the abused children are likely to exclude their primary caregiver from the drawings. The "drawings of the family" of physically and/or sexually abused children significantly evidence a greater emotional distress then the drawings of the non-abused children of the matched control group.

Silverpoint drawings from the Renaissance are among the most precious and rarest treasures of graphical art. Our research group is particularly interested in the analysis of silverpoint drawings by Albrecht Duerer (1471-1528). A very sensitive and non-destructive analytical method, either spatially resolved synchrotron-radiation induced X-ray fluorescence (SY-XRF) or proton-induced X-ray emission (PIXE), is needed to determine the chemical composition of the very faint silver marks on such drawings. Duerer drawings from the collection of the Albertina, Vienna, were analyzed to amend existing data on Duerer drawings. For this purpose an external-beam PIXE setup was installed at the Vienna Environmental Research Accelerator (VERA). It allows to analyze a spot of {approx}0.15 mm on the object in air with 3 MeV protons, and to detect the emitted X-rays that are characteristic for the chemical composition with very good sensitivity and without harming the precious objects. After successful measurements on artificial test samples, four original silverpoint drawings were investigated: two portraits from Albrecht Duerer's very early period (self-portrait and portrait of his father) and two drawings from Duerer's sketch book of his travel to the Netherlands 1520/21.

Turn-by-Turn Imaging of the Transverse Beam Profile in PEP-II

Energy Technology Data Exchange (ETDEWEB)

Fisher, Alan A.; Petree, Mark; /SLAC

2006-12-18

During injection or instability, the transverse profile of an individual bunch in a storage ring can change significantly in a few turns. However, most synchrotron-light imaging techniques are not designed for this time scale. We have developed a novel diagnostic that enhances the utility of a fast gated camera by adding, inexpensively, some features of a dual-axis streak camera, in order to watch the turn-by-turn evolution of the transverse profile, in both x and y. The beam's elliptical profile is reshaped using cylindrical lenses to form a tall and narrow ellipse--essentially the projection of the full ellipse onto one transverse axis. We do this projection twice, by splitting the beam into two paths at different heights, and rotating the ellipse by 90{sup o} on one path. A rapidly rotating mirror scans these vertical ''pencils'' of light horizontally across the photocathode of the camera, which is gated for 3 ns on every Nth ring turn. A single readout of the camera captures 100 images, looking like a stroboscopic photograph of a moving object. We have observed the capture of injected charge into a bunch and the rapid change of beam size at the onset of a fast instability.

1999-01-01

The purposes of this study were to assess client comfort and sleep quality, client physiologic response (skin and respiratory status), the effect on the need for caregiver assistance, and cost when using an automated turning bed. Nonexperimental, evaluative study. Twenty-four adult home or long-term care resident subjects who had a degenerative disease, spinal cord injury, stroke, cerebral palsy, or back surgery. Each subject agreed to use the automated turning bed for four weeks. Researchers completed a demographic survey and skin assessment, and assessed each subject for pressure ulcer risk and for the need of assistance of a care giver for turning before and after the four weeks of using the turning bed. Subjects rated the turning bed in terms of comfort and sleep quality. Subjects rated the turning bed as more comfortable than their own bed and expressed satisfaction at the pain relief attained when on the turning bed. While using the turning bed, there was a significant improvement in sleep quality. No skin breakdown or deterioration in respiratory status occurred. Fewer subjects required the assistance of a caregiver for turning when on the turning bed. This automated turning bed shows great promise in meeting a need for patients with limited mobility whether they are homebound or in a residential community. Future studies that further investigate use of the turning bed for postoperative back patients while still in the acute care setting are indicated. Replicative studies with a larger sample size are also indicated.

Conformational interconversions in peptide beta-turns: analysis of turns in proteins and computational estimates of barriers.

Science.gov (United States)

Gunasekaran, K; Gomathi, L; Ramakrishnan, C; Chandrasekhar, J; Balaram, P

1998-12-18

The two most important beta-turn features in peptides and proteins are the type I and type II turns, which differ mainly in the orientation of the central peptide unit. Facile conformational interconversion is possible, in principle, by a flip of the central peptide unit. Homologous crystal structures afford an opportunity to structurally characterize both possible conformational states, thus allowing identification of sites that are potentially stereochemically mobile. A representative data set of 250 high-resolution (turns that are assigned different conformational types (type I/type II) in related structures. A total of 55 examples of beta-turns were identified as possible candidates for a stereochemically mobile site. Of the 55 examples, 45 could be classified as a potential site for interconversion between type I and type II beta-turns, while ten correspond to flips from type I' to type II' structures. As a further check, the temperature factors of the central peptide unit carbonyl oxygen atom of the 55 examples were examined. The analysis reveals that the turn assignments are indeed reliable. Examination of the secondary structures at the flanking positions of the flippable beta-turns reveals that seven examples occur in the loop region of beta-hairpins, indicating that the formation of ordered secondary structures on either side of the beta-turn does not preclude local conformational variations. In these beta-turns, Pro (11 examples), Lys (nine examples) and Ser (seven examples) were most often found at the i+1 position. Glycine was found to occur overwhelmingly at position i+2 (28 examples), while Ser (seven examples) and Asn (six examples) were amongst the most frequent residues. Activation energy barriers for the interconversion between type I and type II beta-turns were computed using the peptide models Ac-Pro-Aib-NHMe and Ac-Pro-Gly-NHMe within the framework of the AM1 semi-empirical molecular orbital procedure. In order to have a uniform basis for

2014-01-01

Aiming to minimize pain in a hospitalized child, the purpose of this observational study was to describe characteristics of blood samples collected from pre-existing peripheral intravenous (PIV) catheters in pediatric patients. One hundred and fifty blood samples were reviewed for number of unusable samples requiring a specimen to be re-drawn. Success of the blood draw and prevalence of the loss of the PIV following blood collection was also measured. Findings included one clotted specimen, success rate of 91.3%, and 1.3% of PIVs becoming non-functional after collection. Obtaining blood specimens from a pre-existing PIV should be considered in a pediatric patient. Copyright © 2014 Elsevier Inc. All rights reserved.

Japanese children's family drawings and their link to attachment.

Science.gov (United States)

Behrens, Kazuko Y; Kaplan, Nancy

2011-09-01

This study explored the applicability of family drawings as a tool to estimate attachment security in a sample of Japanese six-year-olds (N = 47), applying Kaplan and Main's ( 1986 ) Family Drawing system. Maternal secure/insecure attachment status judged by the Adult Attachment Interview predicted family drawings' secure/insecure distinction produced by Japanese six-year-olds. However, insecure Japanese drawings took forms not seen in the original Berkeley drawings, such as a lineup of faces alone. Further examination of the Japanese children's drawings using global rating scales (Fury, Carlson, & Sroufe, 1997 ) yielded significant gender differences, rarely reported in the attachment literature, with girls scoring higher in scales that predict attachment security and boys scoring higher in scales that predict attachment insecurity. However, attachment security, as captured in the drawings, was not related to attachment security, observed behaviorally using Main and Cassidy's ( 1988 ) sixth-year reunion system. Implications of the findings are discussed in light of measurements, gender, and culture.

Onoue, Yosuke; Kukimoto, Nobuyuki; Sakamoto, Naohisa; Misue, Kazuo; Koyamada, Koji

2017-01-01

An evaluation structure is a hierarchical structure of human cognition extracted from interviews based on the evaluation grid method. An evaluation structure can be defined as a directed acyclic graph (DAG). The authors propose a layer-assignment method that is part of the Sugiyama framework, a popular method for drawing DAGs, to satisfy the requirements for drawing evaluation structures. Their evaluations demonstrate that the layered graph drawing produced by the proposed layer-assignment method is preferred by users and aids in the understanding of evaluation structures.

The transcultural consultation is a form of group therapy which is aimed at families from other countries, using a method which enables children, through drawing, to express themselves in a group. The favoured means of communication for children, drawing is an effective way of liberatingthoughts and giving meaning to family history. Incorporated into the overall narrative, it can thereby be a form of mediation, on condition that it is integrated into the therapeutic programme. This article reflects on the characteristics of the drawings produced by these children who have different cultures and different ways of drawing.

CDD CERN Drawings Directory User's manual Version 1.1

CERN Document Server

Delamare, Christophe; Jeannin, F; Petit, S

1996-01-01

CDD (CERN Drawings Directory) is a multi-platform utility which manages engineering drawings made in any division at CERN. The aim of CDD is not to store the graphical drawing itself, but to store a reference with some information related to the drawing. Access to this data is provided via a graphical user interface which is based upon ORACLE Forms and via WWW. Drawings following different numbering systems and different management rules can be handled by CDD. The only condition is that those particular functionalities are well defined. Several drawing systems have been identified in CERN and therefore considered when designing the application. The current version of CDD focuses on systems EST, LEP, ST-IE, SPS, ST-CE and the experiments ALICE, ATLAS, CMS and LHCb. Other CERN systems could be easily integrated upon demand.

Drawing Myth and History in visual art

Directory of Open Access Journals (Sweden)

Jaime de Córdoba

2009-07-01

Full Text Available After the famous exhibition “Copier créer” curated by Jean Pierre Cuzin in the “Musée du Louvre” in 1993, the practice of drawing art has acquired a renovated interest. This exhibition revised the theoretical concepts introduced by Bober and others in the second half of the XXth century and increased the value of the contribution of drawing in the study of art history instead of the idea of copying. An important catalog and essay by Haverkamp, Begemann and Login, titled “Creative copies”, appeared in 1988 and contained the best examples of the main collections. The last but not least important consequence was the collaboration between international museums, using their own spaces, with contemporary artists. The hermeneutic drawings and paintings by Markus Lüpertz in the Munich Glyptotheck and the exhibition of Giacometti’s drawings shown in the IVAM in 2000 are two excellent examples of the European relevance in this field. I want to analyze here twenty years of drawing done in different museums and institutions around the world and its close relationship with the process of recovering our historical memory by using visual art.

Turning point or selection? The effect of rustication on subsequent health for the Chinese Cultural Revolution cohort.

Science.gov (United States)

Fan, Wen

2016-05-01

During the Chinese Cultural Revolution (1966-76), Chairman Mao sent 17 million urban youth to rural areas to be "reeducated." These "sent-down" youth spent years working alongside peasants, enduring inadequate diets, shelter and medical attention. What were the consequences for subsequent health? Was there a benefit to individuals in the leading or trailing edges of this cohort? Was this a fundamental turning point or were selection process at work? Drawing on the 1994 State and Life Chances in Urban China Survey, I find the health disadvantage at midlife is mostly borne by members of the trailing-edge sub-cohort who lived in the countryside for more than five years. Results from propensity-score analysis indicate a selection process: those who suffered most came from disadvantaged backgrounds. Life chances following the rusticates' return home, however, either do not differ from those who stayed in cities or do not relate to health, refuting the turning-point view, at least in terms of midlife health.

Effect of electroplastic drawing on mechanical, magnetic and electrical properties of wire of 12Kh18N10T and Kh13N13M2 steels was studied. Pulse, direct and alternating currents were used. Direct and alternating current densities were 400 A/mm 2 , mean density of pulse current was 200 A/mm 2 . The investigations have shown that the current density increase results in decreasing the wire strengthening intensity though in increasing plastic properties. As a result of electroplastic drawing the growth of magnetic characteristics of wire occurs

Comparison of the neural basis for imagined writing and drawing.

Science.gov (United States)

Harrington, Greg S; Farias, Dana; Davis, Christine H; Buonocore, Michael H

2007-05-01

Drawing and writing are complex processes that require the synchronization of cognition, language, and perceptual-motor skills. Drawing and writing have both been utilized in the treatment of aphasia to improve communication. Recent research suggests that the act of drawing an object facilitated naming, whereas writing the word diminished accurate naming in individuals with aphasia. However, the relationship between object drawing and subsequent phonological output is unclear. Although the right hemisphere is characteristically mute, there is evidence from split-brain research that the right hemisphere can integrate pictures and words, likely via a semantic network. We hypothesized that drawing activates right hemispheric and left perilesional regions that are spared in aphasic individuals and may contribute to semantic activation that supports naming. Eleven right-handed subjects participated in a functional MRI (fMRI) experiment involving imagined drawing and writing and 6 of the 11 subjects participated in a second fMRI experiment involving actual writing and drawing. Drawing and writing produced very similar group activation maps including activation bilaterally in the premotor, inferior frontal, posterior inferior temporal, and parietal areas. The comparison of drawing vs. writing revealed significant differences between the conditions in areas of the brain known for language processing. The direct comparison between drawing and writing revealed greater right hemisphere activation for drawing in language areas such as Brodmann area (BA) 46 and BA 37.

Actual drawing of histological images improves knowledge retention.

Medical students have to process a large amount of information during the first years of their study, which has to be retained over long periods of nonuse. Therefore, it would be beneficial when knowledge is gained in a way that promotes long-term retention. Paper-and-pencil drawings for the uptake of form-function relationships of basic tissues has been a teaching tool for a long time, but now seems to be redundant with virtual microscopy on computer-screens and printers everywhere. Several studies claimed that, apart from learning from pictures, actual drawing of images significantly improved knowledge retention. However, these studies applied only immediate post-tests. We investigated the effects of actual drawing of histological images, using randomized cross-over design and different retention periods. The first part of the study concerned esophageal and tracheal epithelium, with 384 medical and biomedical sciences students randomly assigned to either the drawing or the nondrawing group. For the second part of the study, concerning heart muscle cells, students from the previous drawing group were now assigned to the nondrawing group and vice versa. One, four, and six weeks after the experimental intervention, the students were given a free recall test and a questionnaire or drawing exercise, to determine the amount of knowledge retention. The data from this study showed that knowledge retention was significantly improved in the drawing groups compared with the nondrawing groups, even after four or six weeks. This suggests that actual drawing of histological images can be used as a tool to improve long-term knowledge retention. © 2015 American Association of Anatomists.

Turn stability in beta-hairpin peptides: Investigation of peptides containing 3:5 type I G1 bulge turns.

Science.gov (United States)

Blandl, Tamas; Cochran, Andrea G; Skelton, Nicholas J

2003-02-01

The turn-forming ability of a series of three-residue sequences was investigated by substituting them into a well-characterized beta-hairpin peptide. The starting scaffold, bhpW, is a disulfide-cyclized 10-residue peptide that folds into a stable beta-hairpin with two antiparallel strands connected by a two-residue reverse turn. Substitution of the central two residues with the three-residue test sequences leads to less stable hairpins, as judged by thiol-disulfide equilibrium measurements. However, analysis of NMR parameters indicated that each molecule retains a significant folded population, and that the type of turn adopted by the three-residue sequence is the same in all cases. The solution structure of a selected peptide with a PDG turn contained an antiparallel beta-hairpin with a 3:5 type I + G1 bulge turn. Analysis of the energetic contributions of individual turn residues in the series of peptides indicates that substitution effects have significant context dependence, limiting the predictive power of individual amino acid propensities for turn formation. The most stable and least stable sequences were also substituted into a more stable disulfide-cyclized scaffold and a linear beta-hairpin scaffold. The relative stabilities remained the same, suggesting that experimental measurements in the bhpW context are a useful way to evaluate turn stability for use in protein design projects. Moreover, these scaffolds are capable of displaying a diverse set of turns, which can be exploited for the mimicry of protein loops or for generating libraries of reverse turns.

Titanium and its alloys have been widely used in aerospace and biomedical industries, however, they are classified as difficult-to-machine materials. In this paper, ultrasonic vibration is imposed on the die to overcome the difficulties during conventional titanium wire drawing processes at the room temperature. Numerical simulations were performed to investigate the variation of axial stress within the contacting region and study the change of the drawing stress with several factors in terms of the longitudinal amplitude and frequency of the applied ultrasonic vibration, the diameter reduction ratio, and the drawing force. An experimental testing equipment was established to measure the drawing torque and rotational velocity of the coiler drum during the wire drawing process. The result indicates the drawing force increases with the growth of the drawing velocity and the reduction ratio, whether with or without vibrations. Application of either form of ultrasonic vibrations contributes to the further decrease of the drawing force, especially the longitudinal vibration with larger amplitude. SEM was employed to detect the surface morphology of the processed wires drawn under the three circumstances. The surface quality of the drawn wires with ultrasonic vibrations was apparently improved compared with those using conventional method. In addition, the longitudinal and torsional composite vibration was more effective for surface quality improvement than pure longitudinal vibration, however, at the cost of weakened drawing force reduction effect.

Cheung, Melissa Mei Yin; Saini, Bandana; Smith, Lorraine

2018-03-01

As an art form, drawings can facilitate the tangible expression of patients' inner images and feelings in a range of health conditions. However, there are currently no published studies investigating adults' perspectives of asthma using drawings. This study aimed to explore how adults' drawings illustrate their perceptions and experiences of asthma. Adults with asthma participated in a one-on-one drawing activity. Analysis was grounded in the participants' accounts of their drawing, which were examined alongside the relevant image. A coding approach was used to cluster thematic material and map the data according to the Common-Sense Model of Self-Regulation (CSM). Eighteen participants took part. Three themes emerged: (1) asthma is constrictive and restrictive, (2) feeling alone, feeling different, and (3) the life journey of asthma. The drawings aligned with several domains of the CSM, in particular consequences. The images drawn by the participants and their subsequent discussions highlighted the prominence of the emotional burden of asthma. The drawings provided powerful and evocative communication of the experience of asthma. Future research using drawings can further both healthcare professionals' and patients' understanding of the physical, social and emotional demands of living with asthma, and support the development of asthma self-management practices.

2018-05-01

The diameter fluctuations of poly(methyl methacrylate) based polymer optical fibers, during drawing processes, have been comprehensively studied. In this study, several drawing parameters were selected for investigation; such as drawing tensions, preform diameters, preform feeding speeds, and argon flows. Varied drawing tensions were used to draw fibers, while other parameters were maintained at constant. At a later stage in the process, micro-structured polymer optical fibers were drawn under optimized drawing conditions. Fiber diameter deviations were reduced to 2.2%, when a 0.2 N drawing tension was employed during the drawing process. Higher drawing tensions led to higher diameter fluctuations. The Young’s modulus of fibers drawn with different tensions was also measured. Our results showed that fiber elasticity increased as drawing tensions decreased. The inhomogeneity of fibers was also determined by comparing the deviation of Young’s modulus.

Petersen, Bent; Lundegaard, Claus; Petersen, Thomas Nordahl

2010-01-01

β-turns are the most common type of non-repetitive structures, and constitute on average 25% of the amino acids in proteins. The formation of β-turns plays an important role in protein folding, protein stability and molecular recognition processes. In this work we present the neural network method NetTurnP, for prediction of two-class β-turns and prediction of the individual β-turn types, by use of evolutionary information and predicted protein sequence features. It has been evaluated against a commonly used dataset BT426, and achieves a Matthews correlation coefficient of 0.50, which is the highest reported performance on a two-class prediction of β-turn and not-β-turn. Furthermore NetTurnP shows improved performance on some of the specific β-turn types. In the present work, neural network methods have been trained to predict β-turn or not and individual β-turn types from the primary amino acid sequence. The individual β-turn types I, I', II, II', VIII, VIa1, VIa2, VIba and IV have been predicted based on classifications by PROMOTIF, and the two-class prediction of β-turn or not is a superset comprised of all β-turn types. The performance is evaluated using a golden set of non-homologous sequences known as BT426. Our two-class prediction method achieves a performance of: MCC  = 0.50, Qtotal = 82.1%, sensitivity  = 75.6%, PPV  = 68.8% and AUC  = 0.864. We have compared our performance to eleven other prediction methods that obtain Matthews correlation coefficients in the range of 0.17 – 0.47. For the type specific β-turn predictions, only type I and II can be predicted with reasonable Matthews correlation coefficients, where we obtain performance values of 0.36 and 0.31, respectively. Conclusion The NetTurnP method has been implemented as a webserver, which is freely available at http://www.cbs.dtu.dk/services/NetTurnP/. NetTurnP is the only available webserver that allows submission of multiple sequences. PMID:21152409

Exploration of polyelectrolytes as draw solutes in forward osmosis processes

KAUST Repository

Ge, Qingchun

2012-03-01

The development of the forward osmosis (FO) process has been constrained by the slow development of appropriate draw solutions. Two significant concerns related to draw solutions are the draw solute leakage and intensiveenergy requirement in recycling draw solutes after the FO process. FO would be much attractive if there is no draw solute leakage and the recycle of draw solutes is easy and economic. In this study, polyelectrolytes of a series of polyacrylic acid sodium salts (PAA-Na), were explored as draw solutes in the FO process. The characteristics of high solubility in water and flexibility in structural configuration ensure the suitability of PAA-Na as draw solutes and their relative ease in recycle through pressure-driven membrane processes. The high water flux with insignificant salt leakage in the FO process and the high salt rejection in recycle processes reveal the superiority of PAA-Na to conventional ionic salts, such as NaCl, when comparing their FO performance via the same membranes. The repeatable performance of PAA-Na after recycle indicates the absence of any aggregation problems. The overall performance demonstrates that polyelectrolytes of PAA-Na series are promising as draw solutes, and the new concept of using polyelectrolytes as draw solutes in FO processes is applicable. © 2011 Elsevier Ltd.

This study aims to evaluate the drawings effectiveness in childhood headache assessment. Headache is a common cause of pain in children. Although drawings have been used in childhood to recognize psychological insights and pain perception, they were rarely used for headache characterization. We collected drawings from 67 subjects with cephalalgia during a 22-month timeframe. The clinical diagnosis was made according to the 2nd edition of The International Headache Classification. Drawings were independently categorized as migraine or tension-type headache (TTH) by two child neuropsychiatrists blinded to the clinical data. Cohen kappa for interrater agreement, sensitivity, specificity, and positive predictive value (PPV) were calculated. Subjects were also divided into three age groups to assess the influence of age. Finally, a control group of 90 subjects was collected and K-means cluster analysis was performed. The drawings had a sensitivity of 85.71 and 81.48%, a specificity of 81.48 and 85.71%, and a PPV of 85.71 and 81.48%, for migraine and TTH diagnosis, respectively. Drawings by the older age group showed the highest predictability degree. Finally, by mean of cluster analysis, 59 of the 67 patients were correctly classified, whereas control subjects were similarly distributed between the two clusters. Drawings are a useful instrument for migraine and TTH differential diagnosis. Thus, we suggest their inclusion in childhood headache diagnostic assessment.

Strauss, Karl F.; Goullioud, Renaud; Cox, Brian; Grimes, James M.

2011-01-01

The design process often involves the use of Excel files during project development. To facilitate communications of the information in the Excel files, drawings are often generated. During the design process, the Excel files are updated often to reflect new input. The problem is that the drawings often lag the updates, often leading to confusion of the current state of the design. The use of this program allows visualization of complex data in a format that is more easily understandable than pages of numbers. Because the graphical output can be updated automatically, the manual labor of diagram drawing can be eliminated. The more frequent update of system diagrams can reduce confusion and reduce errors and is likely to uncover symmetric problems earlier in the design cycle, thus reducing rework and redesign.

Stohr, J.A.

1955-01-01

It describes the study of working and drawing of uranium in γ phase. In a first part, the forgeable characteristics of uranium metal in the three different phases (α, β and γ) are compared by using BASTIEN-PORTEVIN method. The different experiments are testing the behaviour metal in each phase under different stresses and a temperature gradient as slow and shock traction, slow and shock compression, resilience, flexibility. Results show that optimum conditions for uranium drawing is uranium in phase γ. In a second part, it described the drawing method and process. The uranium rods obtained by this technique are of very good quality. In addition, the material wear is very low which permits a low production cost. Finally, the uranium rod physical properties are studied. (M.P.)

Predicting turns in proteins with a unified model.

Directory of Open Access Journals (Sweden)

Qi Song

Full Text Available MOTIVATION: Turns are a critical element of the structure of a protein; turns play a crucial role in loops, folds, and interactions. Current prediction methods are well developed for the prediction of individual turn types, including α-turn, β-turn, and γ-turn, etc. However, for further protein structure and function prediction it is necessary to develop a uniform model that can accurately predict all types of turns simultaneously. RESULTS: In this study, we present a novel approach, TurnP, which offers the ability to investigate all the turns in a protein based on a unified model. The main characteristics of TurnP are: (i using newly exploited features of structural evolution information (secondary structure and shape string of protein based on structure homologies, (ii considering all types of turns in a unified model, and (iii practical capability of accurate prediction of all turns simultaneously for a query. TurnP utilizes predicted secondary structures and predicted shape strings, both of which have greater accuracy, based on innovative technologies which were both developed by our group. Then, sequence and structural evolution features, which are profile of sequence, profile of secondary structures and profile of shape strings are generated by sequence and structure alignment. When TurnP was validated on a non-redundant dataset (4,107 entries by five-fold cross-validation, we achieved an accuracy of 88.8% and a sensitivity of 71.8%, which exceeded the most state-of-the-art predictors of certain type of turn. Newly determined sequences, the EVA and CASP9 datasets were used as independent tests and the results we achieved were outstanding for turn predictions and confirmed the good performance of TurnP for practical applications.

Iwahashi Zenbei's Sunspot Drawings in 1793 in Japan

Hayakawa, Hisashi; Iwahashi, Kiyomi; Tamazawa, Harufumi; Toriumi, Shin; Shibata, Kazunari

2018-01-01

Three Japanese sunspot drawings associated with Iwahashi Zenbei (1756 - 1811) are shown here from contemporary manuscripts and woodprint documents with the relevant texts. We reveal the observational date of one of the drawings to be 26 August 1793, and the overall observations lasted for over a year. Moreover, we identify the observational site for the dated drawing as Fushimi in Japan. We then compare Zenbei's observations with the group sunspot number and the raw group count from the Sunspot Index and Long-term Solar Observations (SILSO) to reveal the context of the data, and we conclude that these drawings fill gaps in our understanding that are due to the fragmental sunspot observations around 1793. These drawings are important as a clue to evaluate astronomical knowledge of contemporary Japan in the late eighteenth century and are valuable as a non-European observation, considering that most sunspot observations up to the middle of the nineteenth century are from Europe.

What 'empirical turn in bioethics'?

Science.gov (United States)

Hurst, Samia

2010-10-01

Uncertainty as to how we should articulate empirical data and normative reasoning seems to underlie most difficulties regarding the 'empirical turn' in bioethics. This article examines three different ways in which we could understand 'empirical turn'. Using real facts in normative reasoning is trivial and would not represent a 'turn'. Becoming an empirical discipline through a shift to the social and neurosciences would be a turn away from normative thinking, which we should not take. Conducting empirical research to inform normative reasoning is the usual meaning given to the term 'empirical turn'. In this sense, however, the turn is incomplete. Bioethics has imported methodological tools from empirical disciplines, but too often it has not imported the standards to which researchers in these disciplines are held. Integrating empirical and normative approaches also represents true added difficulties. Addressing these issues from the standpoint of debates on the fact-value distinction can cloud very real methodological concerns by displacing the debate to a level of abstraction where they need not be apparent. Ideally, empirical research in bioethics should meet standards for empirical and normative validity similar to those used in the source disciplines for these methods, and articulate these aspects clearly and appropriately. More modestly, criteria to ensure that none of these standards are completely left aside would improve the quality of empirical bioethics research and partly clear the air of critiques addressing its theoretical justification, when its rigour in the particularly difficult context of interdisciplinarity is what should be at stake.

Zhang, Kaifeng; Zhang, Tuoda; Wang, Bo

2013-05-01

Recently, electro-plastic forming to be a focus of attention in materials hot processing research area, because it is a sort of energy-saving, high efficient and green manufacturing technology. An electro-thermo-mechanical model can be adopted to carry out the sequence simulation of aluminum matrix composites sheet deep drawing via electro-thermal coupling and thermal-mechanical coupling method. The first step of process is resistance heating of sheet, then turn off the power, and the second step is deep drawing. Temperature distribution of SiCp/2024Al composite sheet by resistance heating and sheet deep drawing deformation were analyzed. During the simulation, effect of contact resistances, temperature coefficient of resistance for electrode material and SiCp/2024Al composite on temperature distribution were integrally considered. The simulation results demonstrate that Sicp/2024Al composite sheet can be rapidly heated to 400° in 30s using resistances heating and the sheet temperature can be controlled by adjusting the current density. Physical properties of the electrode materials can significantly affect the composite sheet temperature distribution. The temperature difference between the center and the side of the sheet is proportional to the thermal conductivity of the electrode, the principal cause of which is that the heat transfers from the sheet to the electrode. SiCp/2024Al thin-wall part can be intactly manufactured at strain rate of 0.08s-1 and the sheet thickness thinning rate is limited within 20%, which corresponds well to the experimental result.

Coopersmith, S; Sakai, D; Beardslee, B; Coopersmith, A

1976-08-01

Figure drawings were obtained from 97 preadolescent males who differed in self and behavioral assessments of self-esteem. These subjects had been selected from a much larger sample and represented five different types of self-esteem. The figure drawings were scored for 15 variables, dealing with formal characteristics, content, and global-interpretations of the total drawings. Five significant differences were obtained, with the content and global-interpretative categories proving more differentiating between self-esteem groups than did the formal characteristics. Behavioral expressions of self-esteem were more associated with figure drawing characteristics than were subjective evaluations. Discussion focuses on the nature of self-concept and self-esteem in children as a sensorimotor rather than symbolic expression.

A New Graph Drawing Scheme for Social Network

Eric Ke Wang

2014-01-01

visualization is employed to extract the potential information from the large scale of social network data and present the information briefly as visualized graphs. In the process of information visualization, graph drawing is a crucial part. In this paper, we study the graph layout algorithms and propose a new graph drawing scheme combining multilevel and single-level drawing approaches, including the graph division method based on communities and refining approach based on partitioning strategy. Besides, we compare the effectiveness of our scheme and FM3 in experiments. The experiment results show that our scheme can achieve a clearer diagram and effectively extract the community structure of the social network to be applied to drawing schemes.

Prediction Model of Cutting Parameters for Turning High Strength Steel Grade-H: Comparative Study of Regression Model versus ANFIS

Directory of Open Access Journals (Sweden)

Adel T. Abbas

2017-01-01

Full Text Available The Grade-H high strength steel is used in the manufacturing of many civilian and military products. The procedures of manufacturing these parts have several turning operations. The key factors for the manufacturing of these parts are the accuracy, surface roughness (Ra, and material removal rate (MRR. The production line of these parts contains many CNC turning machines to get good accuracy and repeatability. The manufacturing engineer should fulfill the required surface roughness value according to the design drawing from first trail (otherwise these parts will be rejected as well as keeping his eye on maximum metal removal rate. The rejection of these parts at any processing stage will represent huge problems to any factory because the processing and raw material of these parts are very expensive. In this paper the artificial neural network was used for predicting the surface roughness for different cutting parameters in CNC turning operations. These parameters were investigated to get the minimum surface roughness. In addition, a mathematical model for surface roughness was obtained from the experimental data using a regression analysis method. The experimental data are then compared with both the regression analysis results and ANFIS (Adaptive Network-based Fuzzy Inference System estimations.

The meanings of consent to the donation of cord blood stem cells: perspectives from an interview-based study of a public cord blood bank in England.

Science.gov (United States)

Busby, Helen

2010-03-01

This paper explores the perspectives of women who have agreed that their umbilical cord blood may be collected for a public 'cord blood bank', for use in transplant medicine or research. Drawing on interview data from 27 mothers who agreed to the collection and use of their umbilical cord blood, these choices and the informed consent process are explored. It is shown that the needs of sick children requiring transplants are prominent in narrative accounts of cord blood banking, together with high expectations for future applications of stem cells. Given this dynamic, a concern arises that the complex and multiple uses of tissues and related data might be oversimplified in the consent process. In conclusion, the positive finding of a commitment to mutuality in cord blood banking among these women is underlined, and its implications for the wider debate on cord blood banking are discussed.

Brief report: human figure drawings by children with Asperger's syndrome.

Science.gov (United States)

Lim, Hui Keow; Slaughter, Virginia

2008-05-01

Twenty-nine children with Asperger's syndrome and 28 typically developing children, matched on gender, chronological age and nonverbal IQ, were asked to produce a free drawing, then requested to draw a person, a house and a tree. The drawings were scored using standardized procedures for assessing accuracy, detail and complexity. There were no differences between the diagnostic groups on the tree or house drawing scores. The human figure drawing scores of children with Asperger's syndrome were significantly lower than those of the typically developing children, and there was a positive correlation between human figure drawing scores and communication sub-scores on the Vineland Adaptive Behaviour Scales, for the Asperger's group. These results suggest that the selective deficit in generating human figure representations may derive from a relative lack of interest in the social world, and/or limited practice in drawing people.

Drawing Disorders in Alzheimer's Disease and Other Forms of Dementia.

Science.gov (United States)

Trojano, Luigi; Gainotti, Guido

2016-04-21

Drawing is a multicomponential process that can be impaired by many kinds of brain lesions. Drawing disorders are very common in Alzheimer's disease and other forms of dementia, and can provide clinical information for the distinction of the different dementing diseases. In our review we started from an overview of the neural and cognitive bases of drawing, and from a recollection of the drawing tasks more frequently used for assessing individuals with dementia. Then, we analyzed drawing disorders in dementia, paying special attention to those observed in Alzheimer's disease, from the prodromal stages of the amnesic mild cognitive impairment to the stages of full-blown dementia, both in the sporadic forms with late onset in the entorhino-hippocampal structures and in those with early onset in the posterior neocortical structures. We reviewed the drawing features that could differentiate Alzheimer's disease from vascular dementia and from the most frequent forms of degenerative dementia, namely frontotemporal dementia and Lewy body disease. Finally, we examined some peculiar aspects of drawing disorders in dementia, such as perseverations, rotations, and closing-in. We argue that a careful analysis of drawing errors helps to differentiate the different forms of dementia more than overall accuracy in drawing.

Children's illness drawings and asthma symptom awareness.

Science.gov (United States)

Gabriels, R L; Wamboldt, M Z; McCormick, D R; Adams, T L; McTaggart, S R

2000-01-01

This study examines the relationship between children's abilities to perceive their symptoms of asthma via several previously researched subjective and objective procedures compared with their performance on a standardized children's drawing task and scale criteria. Results indicated that girls verbalized significantly more emotions about their drawings and were better able to detect airflow changes in their small airways than boys. The Gabriels Asthma Perception Drawing Scales (GAPDS) is a promising clinical tool for assessing children's perceptions and emotions about asthma via nonverbal methods. Varying methods of measuring asthma symptom awareness are not highly correlated; thus, more than one methodology is appropriate for use with children.

Putting a finger on the problem: Finger stick blood draw and immunization at the well-child exam elicit a cortisol response to stress among one-year-old children.

Science.gov (United States)

Kertes, Darlene A; Kamin, Hayley S; Liu, Jingwen; Bhatt, Samarth S; Kelly, Maria

2018-07-01

Research examining stress reactivity of the hypothalamic-pituitary-adrenocortical (HPA) axis in young children has historically been hampered by a lack of reliable methods to invoke a cortisol stress response. This report details an effective method of eliciting a cortisol rise in one-year-old children (N = 83) by modifying and combining two naturalistic stressors previously used with infants and children. Salivary cortisol levels were collected from children before and after a finger stick blood draw and immunizations performed during their one year well-child checkup at their pediatrician's office. Results indicated that the stressor was successful at eliciting a significant cortisol response. An extensive set of potential demographic and clinical confounds were also assessed in order to identify methodological considerations important in studies of infant cortisol. The stress paradigm presented here provides a promising alternative for studies of infant HPA activity to enable investigators to more effectively evaluate early functioning of the biological stress system during this developmentally important life stage.

Directory of Open Access Journals (Sweden)

Alexander Zlotnik

2012-08-01

Full Text Available Brain insults are characterized by a multitude of complex processes, of which glutamate release plays a major role. Deleterious excess of glutamate in the brain’s extracellular fluids stimulates glutamate receptors, which in turn lead to cell swelling, apoptosis, and neuronal death. These exacerbate neurological outcome. Approaches aimed at antagonizing the astrocytic and glial glutamate receptors have failed to demonstrate clinical benefit. Alternatively, eliminating excess glutamate from brain interstitial fluids by making use of the naturally occurring brain-to-blood glutamate efflux has been shown to be effective in various animal studies. This is facilitated by gradient driven transport across brain capillary endothelial glutamate transporters. Blood glutamate scavengers enhance this naturally occurring mechanism by reducing the blood glutamate concentration, thus increasing the rate at which excess glutamate is cleared. Blood glutamate scavenging is achieved by several mechanisms including: catalyzation of the enzymatic process involved in glutamate metabolism, redistribution of glutamate into tissue, and acute stress response. Regardless of the mechanism involved, decreased blood glutamate concentration is associated with improved neurological outcome. This review focuses on the physiological, mechanistic and clinical roles of blood glutamate scavenging, particularly in the context of acute and chronic CNS injury. We discuss the details of brain-to-blood glutamate efflux, auto-regulation mechanisms of blood glutamate, natural and exogenous blood glutamate scavenging systems, and redistribution of glutamate. We then propose different applied methodologies to reduce blood and brain glutamate concentrations and discuss the neuroprotective role of blood glutamate scavenging.

The author credits Pestalozzi with influencing most nineteenth century Continental theorists on the teaching of drawing through his theories, published circa 1800, on drawing as an essential and integral part of each child's education. He analyzes Pestalozzi's approach in the context of his life, times, and general theory of education. (Author/SJL)

Observational drawing biases are predicted by biases in perception: Empirical support of the misperception hypothesis of drawing accuracy with respect to two angle illusions.

Science.gov (United States)

Ostrofsky, Justin; Kozbelt, Aaron; Cohen, Dale J

2015-01-01

We tested the misperception hypothesis of drawing errors, which states that drawing accuracy is strongly influenced by the perceptual encoding of a to-be-drawn stimulus. We used a highly controlled experimental paradigm in which nonartist participants made perceptual judgements and drawings of angles under identical stimulus exposure conditions. Experiment 1 examined the isosceles/scalene triangle angle illusion; congruent patterns of bias in the perception and drawing tasks were found for 40 and 60° angles, but not for 20 or 80° angles, providing mixed support for the misperception hypothesis. Experiment 2 examined shape constancy effects with respect to reproductions of single acute or obtuse angles; congruent patterns of bias in the perception and drawing tasks were found across a range of angles from 29 to 151°, providing strong support for the misperception hypothesis. In both experiments, perceptual and drawing biases were positively correlated. These results are largely consistent with the misperception hypothesis, suggesting that inaccurate perceptual encoding of angles is an important reason that nonartists err in drawing angles from observation.

Malanchini, M.; Tosto, M.G.; Garfield, V.; Czerwik, A.; Dirik, A.; Arden, R.; Malykh, S.

2016-01-01

The study examined the aetiology of individual differences in early drawing and of its longitudinal association with school mathematics. Participants (N = 14,760), members of the Twins Early Development Study, were assessed on their ability to draw a human figure, including number of features, symmetry and proportionality. Human figure drawing was moderately stable across six months (average r = .40). Individual differences in drawing at age 4½ were influenced by genetic (.21), shared environmental (.30) and non-shared environmental (.49) factors. Drawing was related to later (age 12) mathematical ability (average r = .24). This association was explained by genetic and shared environmental factors that also influenced general intelligence. Some genetic factors, unrelated to intelligence, also contributed to individual differences in drawing. PMID:27079561

Machines and Signs A History of the Drawing of Machines

CERN Document Server

Rovida, Edoardo

2013-01-01

This volume addresses the cultural, technical and ethical motivations of the history of drawing of machines and its developments step by step. First it treats drawings without any technical character; then the Renaissance with its new forms of drawing; the 18th century, with orthographic projections, immediately used by industry; the 19th century, including the applications of drawing in industry; and the 20th century, with the standardization institutions and the use of the computer. The role of historical drawings and archives in modern design is also examined. This book is of value to all those who are interested in technical drawing, either from an artistic, from a design, or from an engineering point of view.

The support vector machine approach was introduced to predict the beta-turns in proteins. The overall self-consistency rate by the re-substitution test for the training or learning dataset reached 100%. Both the training dataset and independent testing dataset were taken from Chou [J. Pept. Res. 49 (1997) 120]. The success prediction rates by the jackknife test for the beta-turn subset of 455 tetrapeptides and non-beta-turn subset of 3807 tetrapeptides in the training dataset were 58.1 and 98.4%, respectively. The success rates with the independent dataset test for the beta-turn subset of 110 tetrapeptides and non-beta-turn subset of 30,231 tetrapeptides were 69.1 and 97.3%, respectively. The results obtained from this study support the conclusion that the residue-coupled effect along a tetrapeptide is important for the formation of a beta-turn.

Turn-Based War Chess Model and Its Search Algorithm per Turn

Directory of Open Access Journals (Sweden)

Hai Nan

2016-01-01

Full Text Available War chess gaming has so far received insufficient attention but is a significant component of turn-based strategy games (TBS and is studied in this paper. First, a common game model is proposed through various existing war chess types. Based on the model, we propose a theory frame involving combinational optimization on the one hand and game tree search on the other hand. We also discuss a key problem, namely, that the number of the branching factors of each turn in the game tree is huge. Then, we propose two algorithms for searching in one turn to solve the problem: (1 enumeration by order; (2 enumeration by recursion. The main difference between these two is the permutation method used: the former uses the dictionary sequence method, while the latter uses the recursive permutation method. Finally, we prove that both of these algorithms are optimal, and we analyze the difference between their efficiencies. An important factor is the total time taken for the unit to expand until it achieves its reachable position. The factor, which is the total number of expansions that each unit makes in its reachable position, is set. The conclusion proposed is in terms of this factor: Enumeration by recursion is better than enumeration by order in all situations.

Study on Turn-to-turn Short Circuit On一line Monitoring System for Dry一type Ai r一core Reactor

GAO Zi-wei

2017-04-01

Full Text Available The change of current value caused by turn-to-turn short circuit of dry-type air-core reactor is so little that failure detection is difficult to be carried out. In order to solve this problem，a new on-line monitoring system based on impedance variation of turn-to-turn short circuit is proposed. The numerical method is applied to analyze the variation of equivalent resistance and equivalent reactance when dry-type air-core reactor winding short circuit happens in different places，and the monitoring method based on harmonic analysis method and quasi- synchronization sampling method is analyzed by theory. The hardware system，which takes single-chip microcomputer as the core of data processing and logic control，completes data acquisition of voltage signal and current signal of the reactor. In the respect of software design，the impedance variation will be uploaded to the PC after it has been calculated by using the above monitoring method，and then monitoring of turn-to-turn short circuit fault will be realized. Finally，the design of on-line monitoring system is studied by testing. The research result shows that，the equivalent resistance increases and the equivalent reactance decreases when turn-to-turn short circuit occurs，and the variation of equivalent resistance is more obvious than equivalent reactance. The experiment results prove that this monitoring method is true and the on-line monitoring system is feasible.

Chong, Jimmy; Mackey, Anna H; Stott, N Susan; Broadbent, Elizabeth

2013-06-01

To investigate whether drawings of the self walking by children with cerebral palsy (CP) were associated with walking ability and illness perceptions. This was an exploratory study in 52 children with CP (M:F = 28:24), mean age 11.1 years (range 5-18), who were attending tertiary level outpatient clinics. Children were asked to draw a picture of themselves walking. Drawing size and content was used to investigate associations with clinical walk tests and children's own perceptions of their CP assessed using a CP version of the Brief Illness Perception Questionnaire. Larger drawings of the self were associated with less distance traveled, higher emotional responses to CP, and lower perceptions of pain or discomfort, independent of age. A larger self-to-overall drawing height ratio was related to walking less distance. Drawings of the self confined within buildings and the absence of other figures were also associated with reduced walking ability. Drawing size and content can reflect walking ability, as well as symptom perceptions and distress. Drawings may be useful for clinicians to use with children with cerebral palsy to aid discussion about their condition. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Structural brain differences in relation to expertise have been demonstrated in a number of domains including visual perception, spatial navigation, complex motor skills and musical ability. However no studies have assessed the structural differences associated with representational skills in visual art. As training artists are inclined to be a heterogeneous group in terms of their subject matter and chosen media, it was of interest to investigate whether there would be any consistent changes in neural structure in response to increasing representational drawing skill. In the current study a cohort of 44 graduate and post-graduate art students and non-art students completed drawing tasks. Scores on these tasks were then correlated with the regional grey and white matter volume in cortical and subcortical structures. An increase in grey matter density in the left anterior cerebellum and the right medial frontal gyrus was observed in relation to observational drawing ability, whereas artistic training (art students vs. non-art students) was correlated with increased grey matter density in the right precuneus. This suggests that observational drawing ability relates to changes in structures pertaining to fine motor control and procedural memory, and that artistic training in addition is associated with enhancement of structures pertaining to visual imagery. The findings corroborate the findings of small-scale fMRI studies and provide insights into the properties of the developing artistic brain. Copyright © 2014 Elsevier Inc. All rights reserved.

KG, Ingelheim am Rhein, Germany Background: Given the increasing importance of patient-reported outcomes (PRO in quality medical care, we examined the value and feasibility of an innovative method for assessing patients’ illness perceptions, represented in drawings made by patients with COPD of their lungs. Aim: The aim of our study was: to study patients’ representation of COPD as reflected in their drawings of their lungs; and to examine scores on a validated measure that assesses illness perceptions (ie, Brief Illness Perception Questionnaire [B-IPQ]. Patients and methods: One hundred outpatients with COPD, mean age 70 years, selected from a pharmacy database, participated and 98 filled out the B-IPQ. Eighty-seven patients completed the drawing task. Results: The illness perceptions as reflected in the responses to the B-IPQ scales represented a quite optimistic view of COPD and its consequences. The drawings of the lungs reflected a considerable discordance between patients’ representations and medically accepted representations of lungs of a person with COPD. Conclusion: Assessing illness perceptions in clinical care and research about COPD offers opportunities to identify goals for patient education and self-management. Inviting patients to draw their illness is an innovative and promising approach to assessing PRO. Keywords: COPD, drawings, illness perceptions, PRO, quality of life, self-management

The neural basis for simulated drawing and the semantic implications.

Harrington, Greg S; Farias, Dana; Davis, Christine H

2009-03-01

This functional magnetic resonance imaging (fMRI) study of the mental simulation of drawing (1) investigated the neural substrates of drawing and (2) delineated the semantic aspects of drawing. The goal was to advance our understanding of how drawing a familiar object is linked to lexical semantics and therefore a viable method to use to rehabilitate aphasia. We hypothesized that the semantic aspects of drawing familiar objects compared to drawing non-objects would yield greater activation in the inferior temporal cortex and the inferior frontal cortex of the left hemisphere. To test this hypothesis, eight right-handed subjects performed an fMRI experiment that directly contrasted drawing familiar objects to non-objects using mental imagery. Simulated drawing recruited a large, distributed network of frontal, parietal, and temporal structures. In the contrast comparing drawing familiar objects to non-objects there was stronger activation in the left hemisphere within the inferior temporal, anterior inferior frontal, inferior parietal and superior frontal cortices. The activation within the inferior temporal cortex was associated with visual semantic processing and semantic mediated naming. We suggest that the anterior inferior frontal activation is linked to the inferior temporal cortex and is involved in the selection of specific semantic features of the object as well as retrieval of information regarding the perceptual aspects of the object.

Total bilirubin is beneficial for protecting cardiovascular diseases in adults. The authors aimed to investigate the association of total bilirubin, red blood cell, and hemoglobin levels with the prevalence of high blood pressure in children and adolescents. A total of 3776 students (aged from 6 to 16 years old) were examined using cluster sampling. Pre-high blood pressure and high blood pressure were respectively defined as the point of 90th and 95th percentiles based on the Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents. Both systolic and diastolic blood pressure were standardized into z-scores. Peripheral total bilirubin, red blood cell and hemoglobin levels were significantly correlated with age, and also varied with gender. Peripheral total bilirubin was negatively correlated with systolic blood pressure in 6- and 9-year-old boys, whilst positively correlated with diastolic blood pressure in the 12-year-old boys and 13- to 15-year-old girls (p0.05). Total bilirubin could be weakly correlated with both systolic and diastolic blood pressure, as correlations varied with age and gender in children and adolescents; in turn, the increased levels of red blood cell and hemoglobin are proposed to be positively associated with the prevalence of high blood pressure.

Trust, nostalgia and narrative accounts of blood banking in England in the 21st century.

Science.gov (United States)

Wynne Busby, Helen

2010-07-01

Historically, cultural accounts and descriptions of blood banking in Britain have been associated with notions of altruism, national solidarity and imagined community. While these ideals have continued to be influential, the business of procuring and supplying blood has become increasingly complex. Drawing on interview data with donors in one blood centre in England, this article reports that these donors tend not to acknowledge the complex dynamics of production and exchange in modern blood systems. This, it is argued, is congruent with nostalgic narratives in both popular and official accounts of blood services, which tend to bracket these important changes. A shift to a more open institutional narrative about modern blood services is advocated, as blood services face current and future challenges.

Kowal, Emma; Greenwood, Ashley; McWhirter, Rebekah E

2015-10-01

Public participation in medical research and biobanking is considered key to advances in scientific discovery and translation to improved health care. Cultural concerns relating to blood have been found to affect the participation of indigenous peoples and minorities in research, but such concerns are rarely specified in the literature. This article presents a review of the role of blood in Australian Aboriginal cultures. We discuss the range of meanings and uses of blood in traditional culture, including their use in ceremonies, healing, and sorcery. We draw on more recent literature on Aboriginal Australians and biomedicine to consider how traditional beliefs may be changing over time. These findings provide an empirical basis for researchers and bioethicists to develop culturally grounded strategies to boost the participation of Aboriginal Australians in biomedical research. They also serve as a model for integrating anthropological literature with bioethical concerns that could be applied to other indigenous and minority groups. © The Author(s) 2015.

Identification and red blood cell automated counting from blood smear images using computer-aided system.

Science.gov (United States)

Acharya, Vasundhara; Kumar, Preetham

2018-03-01

Red blood cell count plays a vital role in identifying the overall health of the patient. Hospitals use the hemocytometer to count the blood cells. Conventional method of placing the smear under microscope and counting the cells manually lead to erroneous results, and medical laboratory technicians are put under stress. A computer-aided system will help to attain precise results in less amount of time. This research work proposes an image-processing technique for counting the number of red blood cells. It aims to examine and process the blood smear image, in order to support the counting of red blood cells and identify the number of normal and abnormal cells in the image automatically. K-medoids algorithm which is robust to external noise is used to extract the WBCs from the image. Granulometric analysis is used to separate the red blood cells from the white blood cells. The red blood cells obtained are counted using the labeling algorithm and circular Hough transform. The radius range for the circle-drawing algorithm is estimated by computing the distance of the pixels from the boundary which automates the entire algorithm. A comparison is done between the counts obtained using the labeling algorithm and circular Hough transform. Results of the work showed that circular Hough transform was more accurate in counting the red blood cells than the labeling algorithm as it was successful in identifying even the overlapping cells. The work also intends to compare the results of cell count done using the proposed methodology and manual approach. The work is designed to address all the drawbacks of the previous research work. The research work can be extended to extract various texture and shape features of abnormal cells identified so that diseases like anemia of inflammation and chronic disease can be detected at the earliest.

Drawing a dog: The role of working memory and executive function.

Science.gov (United States)

Panesi, Sabrina; Morra, Sergio

2016-12-01

Previous research suggests that young children draw animals by adapting their scheme for the human figure. This can be considered an early form of drawing flexibility. This study investigated preschoolers' ability to draw a dog that is different from the human figure. The role of working memory capacity and executive function was examined. The participants were 123 children (36-73 months old) who were required to draw both a person and a dog. The dog figure was scored on a list of features that could render it different from the human figure. Regression analyses showed that both working memory capacity and executive function predicted development in the dog drawing; the dog drawing score correlated with working memory capacity and executive function, even partialling out age, motor coordination, and drawing ability (measured with Goodenough's Draw-a-Man test). These results suggest that both working memory capacity and executive function play an important role in the early development of drawing flexibility. The implications regarding executive functions and working memory are also discussed. Copyright © 2016 Elsevier Inc. All rights reserved.

Reliability of the wire drawing dies

International Nuclear Information System (INIS)

Sheikh, A.K.; Khany, S.E.

1993-01-01

A wear based model is proposed for the dies used in wire drawing process. Using this wear model, it is possible to predict life of the die corresponding to a wear limit criterion. Since various quantities in the model are random in nature the resulting die life will also be random quantity characterized by an appropriate distribution. Using a probabilistic characterization of the parameters of the predictive model, Monte Carlo simulations were conducted to establish the die life distribution. To asses the sensitivity of life distribution with respect to various contributing variables (parameters), the simulation runs were conducted at different levels of these variables (parameters). It is shown that wire drawing die life is Weibull distributed. To compare the simulated results with actual time to failure, data of dies was obtained from a large wire drawing company and was compared with corresponding scenario generated by Monte Carlo simulation. Results obtained by Monte Carlo simulations were very close to the actual time to failure data. (author)

Young children show representational flexibility when interpreting drawings.

Science.gov (United States)

Allen, Melissa L; Nurmsoo, Erika; Freeman, Norman

2016-02-01

Drawings can be ambiguous and represent more than one entity. In three experiments, we examine whether young children show representational flexibility by allowing one picture to be called by a second name. We also evaluate the hypothesis that children who are representationally flexible see the artist's intention as binding, rather than changeable. In Experiment 1, an artist declared what she intended to draw (e.g. a balloon) but then produced an ambiguous drawing. Children were asked whether the drawings could be interpreted differently (e.g. 'could this be a lollipop?') in the presence of a perceptually similar or dissimilar distractor (e.g., lollipop or snake). Six-year-olds accepted two labels for drawings in both conditions, but four-year-olds only did so in the dissimilar condition. Experiment 2 probed each possible interpretation more deeply by asking property questions (e.g., 'does it float?, does it taste good?'). Preschoolers who understood that the ambiguous drawing could be given two interpretations nevertheless mostly endorsed only properties associated with the prior intent. Experiment 3 provided converging evidence that 4-year-olds were representationally flexible using a paradigm that did not rely upon modal questioning. Taken together, our results indicate that even 4-year-olds understand that pictures may denote more than one referent, they still think of the symbol as consistent with the artist's original intention.

2010-01-01

The contribution deals with the transformation of engineering drawings in a paper form into a 3D computer representation. A 3D computer model can be further processed in CAD/CAM system, it can be modified, archived, and a technical drawing can be then generated from it as well. The transformation process from paper form to the data one is a complex and difficult one, particularly owing to the different types of drawings, forms of displayed objects and encountered errors and deviations from technical standards. The algorithm for 3D model generating from an orthogonal vector input representing a simplified technical drawing of the rotational part is described in this contribution. The algorithm was experimentally implemented as ObjectARX application in the AutoCAD system and the test sample as the representation of the rotational part was used for verificaton.

Facilitating complex shape drawing in Williams syndrome and typical development.

Science.gov (United States)

Hudson, Kerry D; Farran, Emily K

2013-07-01

Individuals with Williams syndrome (WS) produce drawings that are disorganised, likely due to an inability to replicate numerous spatial relations between parts. This study attempted to circumvent these drawing deficits in WS when copying complex combinations of one, two and three shapes. Drawing decisions were reduced by introducing a number of facilitators, for example, by using distinct colours and including facilitatory cues on the response sheet. Overall, facilitation improved drawing in the WS group to a comparable level of accuracy as typically developing participants (matched for non-verbal ability). Drawing accuracy was greatest in both groups when planning demands (e.g. starting location, line lengths and changes in direction) were reduced by use of coloured figures and providing easily distinguished and clearly grouped facilitatory cues to form each shape. This study provides the first encouraging evidence to suggest that drawing of complex shapes in WS can be facilitated; individuals with WS might be receptive to remediation programmes for drawing and handwriting.

2015-06-01

In typically developing children, drawing development occurs in stages from uncontrolled strokes to complex drawing. In this study, we examined drawing development in children with neurodevelopmental delay (NDD). In order to do so, we observed the influence of age, intraventricular hemorrhage (IVH) and gender on the development of drawing skills. The sample consisted of 52 children with NDD, aged 2 years and 6 months to 5 years. All children were hospitalized for multidisciplinary team monitoring and developmental support. The evaluation of drawing development was administered by giving each child a blank A4 paper and the instruction to draw anything they wanted. All of the drawings were scored satisfactory or unsatisfactory. Descriptive statistics was employed on all relevant data to show results in frequencies and percentages. In order to determine differences between groups, the χ2-test was administered. The results showed greatest difference in drawing in children aged from 3 years to 3 years and 11 months. Children with lower IVH had better drawing scores than children with higher IVH levels. According to gender dissimilarities, a difference was found showing girls to have better drawing skills than boys. All study results pointed to the importance of early rehabilitation and continuous structured work with children with NDD.

Full Text Available For solving problems such as short turn-off time, high linear degree of falling edge, measurement of turn-off time and influence of primary signals for transient electromagnetic transmitter, and restrictions because of the environmental conditions of underground coal mine, this thesis aims at designing a new transient electromagnetic transmitter system suitable for coal mine. Supported by damping absorption circuit, such system applies small volume, sectional transmitting coil, with features of short turn-off time, high linear degree of current falling edge. It uses the transmitter monitoring circuit, which accurately measures turn-off time and simultaneously records the current value changes after turn-off, thus to eliminate the influence of primary field as well as to restore earlier secondary field signals for reference and finally to improve the ability to detect the shallow structure. It turns out that the new system has a shorter turn-off time, a higher linear degree of current falling and more accurate data record of turn-off current.

Our goal was to gain a better understanding of how protein stability can be increased by improving beta-turns. We studied 22 beta-turns in nine proteins with 66-370 residues by replacing other residues with proline and glycine and measuring the stability. These two residues are statistically preferred in some beta-turn positions. We studied: Cold shock protein B (CspB), Histidine-containing phosphocarrier protein, Ubiquitin, Ribonucleases Sa2, Sa3, T1, and HI, Tryptophan synthetase alpha-subunit, and Maltose binding protein. Of the 15 single proline mutations, 11 increased stability (Average = 0.8 +/- 0.3; Range = 0.3-1.5 kcal/mol), and the stabilizing effect of double proline mutants was additive. On the basis of this and our previous work, we conclude that proteins can generally be stabilized by replacing nonproline residues with proline residues at the i + 1 position of Type I and II beta-turns and at the i position in Type II beta-turns. Other turn positions can sometimes be used if the phi angle is near -60 degrees for the residue replaced. It is important that the side chain of the residue replaced is less than 50% buried. Identical substitutions in beta-turns in related proteins give similar results. Proline substitutions increase stability mainly by decreasing the entropy of the denatured state. In contrast, the large, diverse group of proteins considered here had almost no residues in beta-turns that could be replaced by Gly to increase protein stability. Improving beta-turns by substituting Pro residues is a generally useful way of increasing protein stability. 2009 Wiley-Liss, Inc.

An observational study was conducted using a structured observation scheme to assess compliance with the local phlebotomy guideline, to identify necessary focus items, and to investigate whether adherence to the phlebotomy guideline improved. The questionnaire from the EFLM Working Group for the Preanalytical Phase was adapted to local procedures. A pilot study of three months duration was conducted. Based on this, corrective actions were implemented and a follow-up study was conducted. All phlebotomists at the Department of Clinical Biochemistry and Pharmacology were observed. Three blood collections by each phlebotomist were observed at each session conducted at the phlebotomy ward and the hospital wards, respectively. Error frequencies were calculated for the phlebotomy ward and the hospital wards and for the two study phases. A total of 126 blood drawings by 39 phlebotomists were observed in the pilot study, while 84 blood drawings by 34 phlebotomists were observed in the follow-up study. In the pilot study, the three major error items were hand hygiene (42% error), mixing of samples (22%), and order of draw (21%). Minor significant differences were found between the two settings. After focus on the major aspects, the follow-up study showed significant improvement for all three items at both settings (P < 0.01, P < 0.01, and P = 0.01, respectively). Continuous quality control of the phlebotomy procedure revealed a number of items not conducted in compliance with the local phlebotomy guideline. It supported significant improvements in the adherence to the recommended phlebotomy procedures and facilitated documentation of the phlebotomy quality.

A tree-drawing test acts as both a projective psychological examination as well as a supplementary psychodiagnostic tool. There is little information relating the characteristics of schizophrenia and the tree-drawing test. The present study compared the structural and morphological differences in the results of the tree-drawing test between schizophrenic patients and healthy individuals, as well as between schizophrenic patients who responded well to treatment and those who responded poorly. The subjects included 202 chronic schizophrenic patients and 113 healthy individuals. The schizophrenic patients were categorized as 'good responders' or 'poor responders' based on their response to medical treatments. The tree-drawing test was performed on all subjects. The tree drawn by each subject was analyzed structurally and morphologically. There were significant differences between the trunk and branches drawn by schizophrenic patients and those drawn by healthy controls. There were no significant differences between the good responders and the poor responders in any aspect of the tree drawings. Multiple regression models showed that the ratio of the tree area to the total area of the drawing paper, the width of the trunk, the trunk base opening, and the size of the branch ends were significantly associated with schizophrenia. The present study suggests that the trees drawn by schizophrenic patients are significantly different from those drawn by healthy individuals, but among schizophrenic patients, it is difficult to distinguish between good responders and poor responders using the tree-drawing test.

The present study examined the relationship between directionality of drawing movements and the orientation of drawn products in right-handed adults and young children for 27 Japanese kindergartners and 29 Japanese university students who were asked to draw with each hand fishes in side view and circles from several starting points. Significant values of chi2 for distributions of frequencies of orientation of the fish drawings and the direction of circular drawing movement indicated that adult right-handers drawing the fish facing to the left tended to draw a circle clock-wise when they drew with the dominant hand, while there was no such significant relationship in young children's drawings. This result may suggest that the reading and writing habits may be implicated in the direction of drawing movements with the dominant hand, and this directional bias of drawing movement in the dominant hand can appear in the orientation of finished drawings.

Experimental and numerical study of micro deep drawing

Directory of Open Access Journals (Sweden)

Luo Liang

2015-01-01

Full Text Available Micro forming is a key technology for an industrial miniaturisation trend, and micro deep drawing (MDD is a typical micro forming method. It has great advantages comparing to other micro manufacturing methods, such as net forming ability, mass production potential, high product quality and complex 3D metal products fabrication capacity. Meanwhile, it is facing difficulties, for example the so-called size effects, once scaled down to micro scale. To investigate and to solve the problems in MDD, a combined micro blanking-drawing machine is employed and an explicit-implicit micro deep drawing model with a voronoi blank model is developed. Through heat treatment different grain sizes can be obtained, which affect material's properties and, consequently, the drawing process parameters, as well as produced cups' quality. Further, a voronoi model can provide detailed material information in simulation, and numerical simulation results are in accordance with experimental results.

In troublesome situations, each of us uses verbal communication carefully, at times diminishing our meaning with words of little significance. However, since the need to communicate remains a part of us, body language or other forms of expression are put into use. Inside a hospital a child is always a stranger with regards to the uneasiness that accompanies his/her experience. Because diagnostic and therapeutic ends are the primary concern of the health care professionals, there is often little sign of affection in their impersonal gestures, glances and body language. Graphic and pictorial communication, therefore, hold great importance for sick children since this is an area they have easier access to, and that they cultivate at school and through play. This activity fulfills their innate need to communicate with themselves and with others. Children express themselves through drawings, using them as a stage to dramatize their needs, wishes anxieties, and joys. When in hospital, children are afraid, and they feel embarrassed around strangers and even parents, especially when the parents are speaking with their caregivers. The children are afraid of making a poor impression and of being rejected by adults, of being considered inadequate and untruthful. Their need for truth and for communication unfolds through artistic expression, and this is the basis of art therapy. The opportunity to express themselves through drawings is what makes the ill child his/her won therapeutic agent through a self-healing mechanism. This may be further guided so as to lead to an increase in self-esteem, which in turn will lead to both enhancement of their full expressive possibilities and to positive feedback of their self-image. In addition to verbal language itself, art therapy is the preferred and ideal means to communicate following the rules of "narrative-based medicine", and to understand children.

Anticipation in turn-taking: mechanisms and information sources.

Science.gov (United States)

Riest, Carina; Jorschick, Annett B; de Ruiter, Jan P

2015-01-01

During conversations participants alternate smoothly between speaker and hearer roles with only brief pauses and overlaps. There are two competing types of accounts about how conversationalists accomplish this: (a) the signaling approach and (b) the anticipatory ('projection') approach. We wanted to investigate, first, the relative merits of these two accounts, and second, the relative contribution of semantic and syntactic information to the timing of next turn initiation. We performed three button-press experiments using turn fragments taken from natural conversations to address the following questions: (a) Is turn-taking predominantly based on anticipation or on reaction, and (b) what is the relative contribution of semantic and syntactic information to accurate turn-taking. In our first experiment we gradually manipulated the information available for anticipation of the turn end (providing information about the turn end in advance to completely removing linguistic information). The results of our first experiment show that the distribution of the participants' estimation of turn-endings for natural turns is very similar to the distribution for pure anticipation. We conclude that listeners are indeed able to anticipate a turn-end and that this strategy is predominantly used in turn-taking. In Experiment 2 we collected purely reacted responses. We used the distributions from Experiments 1 and 2 together to estimate a new dependent variable called Reaction Anticipation Proportion. We used this variable in our third experiment where we manipulated the presence vs. absence of semantic and syntactic information by low-pass filtering open-class and closed class words in the turn. The results suggest that for turn-end anticipation, both semantic and syntactic information are needed, but that the semantic information is a more important anticipation cue than syntactic information.

School-age children's fears, anxiety, and human figure drawings.

Carroll, M K; Ryan-Wenger, N A

1999-01-01

The purpose of this study was to identify the fears of school-age children and determine the relationship between fear and anxiety. A descriptive, correlational, secondary analysis study was conducted using a convenience sample of 90 children between the ages of 8 and 12 years. Each child was instructed to complete the Revised Children's Anxiety Scale and then answer questions from a structured interview. On completion, each child was instructed to draw a human figure drawing. Frequency charts and correlational statistics were used to analyze the data. Findings indicated that the most significant fears of the boys were in the categories of animals, safety, school, and supernatural phenomena, whereas girls were more fearful of natural phenomena. High correlations existed between anxiety scores and the number of fears and emotional indicators on human figure drawings. Because human figure drawings are reliable tools for assessing anxiety and fears in children, practitioners should incorporate these drawings as part of their routine assessments of fearful children.

Feedback control in deep drawing based on experimental datasets

Fischer, P.; Heingärtner, J.; Aichholzer, W.; Hortig, D.; Hora, P.

2017-09-01

In large-scale production of deep drawing parts, like in automotive industry, the effects of scattering material properties as well as warming of the tools have a significant impact on the drawing result. In the scope of the work, an approach is presented to minimize the influence of these effects on part quality by optically measuring the draw-in of each part and adjusting the settings of the press to keep the strain distribution, which is represented by the draw-in, inside a certain limit. For the design of the control algorithm, a design of experiments for in-line tests is used to quantify the influence of the blank holder force as well as the force distribution on the draw-in. The results of this experimental dataset are used to model the process behavior. Based on this model, a feedback control loop is designed. Finally, the performance of the control algorithm is validated in the production line.

The drawings of fossils by Robert Hooke and Richard Waller that were the basis of the engravings in Hooke's Posthumous works (1705) are published here for the first time. The drawings show that both Hooke and Waller were proficient draftsmen with a keen eye for the details of petrified objects. These drawings provided Hooke with a polemic edge in making the case for the organic origins of ‘figured stones’.

Breaking New Ground with High Resolution Turn-By-Turn BPMs at the ESRF

CERN Document Server

Farvacque, L; Scheidt, K

2001-01-01

This High-Resolution, Turn-by-Turn BPM system is a low-cost extension to the existing BPM system, based on the RF-multiplexing concept, used for slow Closed-Orbit measurements. With this extension Beam Position measurements in both planes, at all (224) BPMs in the 844 m ESRF Storage Ring, for up to 2048 Orbit Turns with 1 μm resolution are performed. The data acquisition is synchronised to a single, flat 1 μs, transverse deflection kick to the 1μs beamfill in the 2.8μs revolution period. The high quality of this synchronisation, together with the good reproducibility of the deflection kick and the overall stability of the Closed Orbit beam allows to repeat the kick and acquisition in many cycles. The subsequent averaging of the data obtained in these cycles yields the 1um resolution. The latter allows lattice measurements with high precision such as the localisation of very small focussing errors and modulation in Beta values and phase advances. It also finds an unique ...

Laterality of the lower limbs and carving turns

Directory of Open Access Journals (Sweden)

F Vaverka

2010-06-01

Full Text Available The aim of this study is to discover whether the lateral preference of the lower limbs influences the execution of successive carving turns or not. Six skilled skiers (men, right lower limb preference, age 26.5±1.61 years old, height 1.80±0.04 m, body weight 78.83±5.46 kg executed 30 (18 left, 12 right symmetrical carving turns. Kinetic analysis of the final vertical component of reaction force FZ(t measured dynamometrically provided the information about the time of initiation and steering phases of the turn and the maximum force, average force and force impulse. Differences between right and left turns are not statistically significant. Factual analyses of the magnitude of measured variables confirmed that left turns were found to have a longer duration, a shorter initiation and longer steering phase, and higher level of produced force and force impulse in comparison with right turns. Based on the results it can be concluded that the turns where the outer leg is the preferred limb are preferentially used to regulate the speed of the ride. The study of laterality in symmetrical carving turns has proven that lateral preference of lower extremities influences the execution of the turn also by expert skiers.

Not much is known about how children perceive the quality of care that they receive in hospitals. This study set out to describe elements of quality in children's drawings of an ideal hospital. Thirty-five drawings were collected from children aged between 4 and 11 years during their stay in a university hospital in Finland. They were coded using the method of content analysis. The two main categories extracted from the analysis were the environment and the people of their ideal hospital. The emphasis was on the environment; patients, parents, and nurses appeared less frequently in the drawings. The findings showed that children are capable of offering valuable insights into the elements of quality through the medium of drawing.

AIM: To study the blood-brain barrier integrity in prehepatic portal hypertensive rats induced by partial portal vein ligation, at 14 and 40 d after ligation when portal pressure is spontaneously normalized. METHODS: Adult male Wistar rats were divided into four groups: Group I: Sham14d , sham operated; Group II: PH14d , portal vein stenosis; (both groups were used 14 days after surgery); Group III: Sham40d, Sham operated and Group IV: PH40d Portal vein stenosis (Groups II and IV used 40 d after surgery). Plasma ammonia, plasma and cerebrospinal fluid protein and liver enzymes concentrations were determined. Trypan and Evans blue dyes, systemically injected, were investigated in hippocampus to study blood-brain barrier integrity. Portal pressure was periodically recorded. RESULTS: Forty days after stricture, portal pressure was normalized, plasma ammonia was moderately high, and both dyes were absent in central nervous system parenchyma. All other parameters were reestablished. When portal pressure was normalized and ammonia level was lowered, but not normal, the altered integrity of blood-brain barrier becomes reestablished. CONCLUSION: The impairment of blood-brain barrier and subsequent normalization could be a mechanism involved in hepatic encephalopathy reversibility. Hemodynamic changes and ammonia could trigger blood-brain barrier alterations and its reestablishment. PMID:16552803

Historically, the readings of Wittgenstein in the social sciences have taken...... of the linguistic turn in social theory, the linguistic turn is a double-edged sword of both profound insights and limits; the claim is that the limits of the linguistic turn are the strengths of functionalist, structuralist and materialist approaches to the social sciences. The approach of the critical turn...... is to develop a more comprehensive social theory that is sensitive to these strengths and thus supersedes the limits of the linguistic turn. This paper suggests a different approach. Against the critical turn, the paper argues that the limits of the linguistic turn are identical with the very assumptions...

The aim of this study was to evaluate the use of the Diagnostic Drawing Series (DDS) as a screening tool for the breast cancer patients with psychological distress. All of 64 patients with breast cancer participated in this study. Patients' depressive and anxiety symptoms were assessed using Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) when the DDS was applied to the partipicants. Depressed patients used more enclosure in the Feeling drawings ( P = 0.002) and tilt in Free drawings ( P = 0.048). Patients with anxiety drew a picture over 67% of the paper ( P = 0.015) in Tree drawing and more medium pressure ( P = 0.049) in Feeling drawings. Thirty four subjects (77.3%) of unstable emotion group used over 67% of the space ( P = 0.002). More Landscapes were observed in the Feeling drawings of unstable patients ( P = 0.042). These results suggested that DDS could be used as a supplemental screening tool for psychological distress in breast cancer patients.

MAPMAKER is one of the most widely used computer software package for constructing genetic linkage maps.However, the PC version, MAPMAKER 3.0 for PC, could not draw the genetic linkage maps that its Macintosh version, MAPMAKER 3.0 for Macintosh,was able to do. Especially in recent years, Macintosh computer is much less popular than PC. Most of the geneticists use PC to analyze their genetic linkage data. So a new computer software to draw the same genetic linkage maps on PC as the MAPMAKER for Macintosh to do on Macintosh has been crying for. Microsoft Excel,one component of Microsoft Office package, is one of the most popular software in laboratory data processing. Microsoft Visual Basic for Applications (VBA) is one of the most powerful functions of Microsoft Excel. Using this program language, we can take creative control of Excel, including genetic linkage map construction, automatic data processing and more. In this paper, a Microsoft Excel macro called MapDraw is constructed to draw genetic linkage maps on PC computer based on given genetic linkage data. Use this software,you can freely construct beautiful genetic linkage map in Excel and freely edit and copy it to Word or other application. This software is just an Excel format file. You can freely copy it from ftp://211.69.140.177 or ftp://brassica.hzau.edu.cn and the source code can be found in Excel's Visual Basic Editor.

Characterization of beta-turn and Asx-turns mimicry in a model peptide: stabilization via C--H . . . O interaction.

Science.gov (United States)

Thakur, A K; Kishore, R

2006-04-15

The chemical synthesis and single-crystal X-ray diffraction analysis of a model peptide, Boc-Thr-Thr-NH2 (1) comprised of proteinogenic residues bearing an amphiphilic Cbeta -stereogenic center, has been described. Interestingly, the analysis of its molecular structure revealed the existence of a distinct conformation that mimics a typical beta-turn and Asx-turns, i.e., the two Thr residues occupy the left- and right-corner positions. The main-chain torsion angles of the N- and C-terminal residues i.e., semiextended: phi = -68.9 degrees , psi = 128.6 degrees ; semifolded: phi = -138.1 degrees , psi = 2.5 degrees conformations, respectively, in conjunction with a gauche- disposition of the obligatory C-terminus Thr CgammaH3 group, characterize the occurrence of the newly described beta-turn- and Asx-turns-like topology. The preferred molecular structure is suggested to be stabilized by an effective nonconventional main-chain to side-chain Ci=O . . . H--Cgamma(i+2)-type intraturn hydrogen bond. Noteworthy, the observed topology of the resulting 10-membered hydrogen-bonded ring is essentially similar to the one perceived for a classical beta-turn and the Asx-turns, stabilized by a conventional intraturn hydrogen bond. Considering the signs as well as magnitudes of the backbone torsion angles and the orientation of the central peptide bond, the overall mimicked topology resembles the type II beta-turn or type II Asx-turns. An analysis of Xaa-Thr sequences in high-resolution X-ray elucidated protein structures revealed the novel topology prevalence in functional proteins (unpublished). In view of indubitable structural as well as functional importance of nonconventional interactions in bioorganic and biomacromolecules, we intend to highlight the participation of Thr CgammaH in the creation of a short-range C=O . . . H--Cgamma -type interaction in peptides and proteins. Copyright 2006 Wiley Periodicals, Inc.

Characterization of fine motor development: dynamic analysis of children's drawing movements.

In this study, we investigated children's fine motor development by analyzing drawing trajectories, kinematics and kinetics. Straight lines drawing task and circles drawing task were performed by using a force sensitive tablet. Forty right-handed and Chinese mother-tongue students aged 6-12, attending classes from grade 1 to 5, were engaged in the experiment. Three spatial parameters, namely cumulative trace length, vector length of straight line and vertical diameter of circle were determined. Drawing duration, mean drawing velocity, and number of peaks in stroke velocity profile (NPV) were derived as kinematic parameters. Besides mean normal force, two kinetic indices were proposed: normalized force angle regulation (NFR) and variation of fine motor control (VFC) for circles drawing task. The maturation and automation of fine motor ability were reflected by increased drawing velocity, reduced drawing duration, NPV and NFR, with decreased VFC in circles drawing task. Grade and task main effects as well as significant correlations between age and parameters suggest that factors such as schooling, age and task should be considered in the assessment of fine motor skills. Compared with kinematic parameters, findings of NFR and VFC revealed that kinetics is another important perspective in the analysis of fine motor movement. Copyright © 2014 Elsevier B.V.

High accuracy scanned sunspot drawings handwritten characters recognition is an issue of critical importance to analyze sunspots movement and store them in the database. This paper presents a robust deep learning method for scanned sunspot drawings handwritten characters recognition. The convolution neural network (CNN) is one algorithm of deep learning which is truly successful in training of multi-layer network structure. CNN is used to train recognition model of handwritten character images which are extracted from the original sunspot drawings. We demonstrate the advantages of the proposed method on sunspot drawings provided by Chinese Academy Yunnan Observatory and obtain the daily full-disc sunspot numbers and sunspot areas from the sunspot drawings. The experimental results show that the proposed method achieves a high recognition accurate rate.

METHODICAL MODEL FOR TEACHING BASIC SKI TURN

Full Text Available With the aim of forming an expert model of the most important operators for basic ski turn teaching in ski schools, an experiment was conducted on a sample of 20 ski experts from different countries (Croatia, Bosnia and Herzegovina and Slovenia. From the group of the most commonly used operators for teaching basic ski turn the experts picked the 6 most important: uphill turn and jumping into snowplough, basic turn with hand sideways, basic turn with clapping, ski poles in front, ski poles on neck, uphill turn with active ski guiding. Afterwards, ranking and selection of the most efficient operators was carried out. Due to the set aim of research, a Chi square test was used, as well as the differences between frequencies of chosen operators, differences between values of the most important operators and differences between experts due to their nationality. Statistically significant differences were noticed between frequencies of chosen operators (c2= 24.61; p=0.01, while differences between values of the most important operators were not obvious (c2= 1.94; p=0.91. Meanwhile, the differences between experts concerning thier nationality were only noticeable in the expert evaluation of ski poles on neck operator (c2=7.83; p=0.02. Results of current research are reflected in obtaining useful information about methodological priciples of learning basic ski turn organization in ski schools.

Sheet metal forming is one of the major processes in manufacturing and is broadly used due to its high degree of design flexibility and low cost. In the sheet metal forming process, draw-in (planar movement of a sheet periphery) frequently occurs and is one of the most dominated indicators on the success of a forming process. Currently, monitoring and controlling draw-in during each stamping operation requires either time-consuming setup or a significant die modification. Most devices have been used only in laboratory settings. Our goal is to design a draw-in sensor providing high sensitivity in monitoring; ease of setup, measurement and controlling; and eventually be implemented in industry. Our design is based on the mutual inductance principle, which we considered physical factors affecting the characteristics of the draw-in sensor. Two different configurations, single-transducer and double-transducer of our draw-in sensors have been designed and tested. The results showed good linearity, especially for the double-transducer case. The output of the draw-in sensor was affected by the type of sheet metal, dimension of the transducer, and the distance between the transducer and the testing sheet metal. It was found that the result was insensitive to the waviness of the sheet metal if sheet thickness was thin. The invention, implementation, and integration of the draw-in sensor will have an enormous impact on revolutionizing the control of stamping process, will provide solid ground for process variation and uncertainty studies, and ultimately will affect the design decision process

Preanalytical Biases in the Measurement of Human Blood Sphingolipids

Full Text Available Dysregulation of blood sphingolipids is an emerging topic in clinical science. The objective of this study was to determine preanalytical biases that typically occur in clinical and translational studies and that influence measured blood sphingolipid levels. Therefore, we collected blood samples from four healthy male volunteers to investigate the effect of storage conditions (time, temperature, long-term storage, freeze–thaw cycles, blood drawing (venous or arterial sampling, prolonged venous compression, and sample preparation (centrifugation, freezing on sphingolipid levels measured by LC-MS/MS. Our data show that sphingosine 1-phosphate (S1P and sphinganine 1-phosphate (SA1P were upregulated in whole blood samples in a time- and temperature-dependent manner. Increased centrifugation at higher speeds led to lower amounts of S1P and SA1P. All other preanalytical biases did not significantly alter the amounts of S1P and SA1P. Further, in almost all settings, we did not detect differences in (dihydroceramide levels. In summary, besides time-, temperature-, and centrifugation-dependent changes in S1P and SA1P levels, sphingolipids in blood remained stable under practically relevant preanalytical conditions.

Schaer, K; Jahn, G; Lotze, M

2012-07-15

Neural processes for naturalistic drawing might be discerned into object recognition and analysis, attention processes guiding eye hand interaction, encoding of visual features in an allocentric reference frame, a transfer into the motor command and precise motor guidance with tight sensorimotor feedback. Cerebral representations in a real life paradigm during naturalistic drawing have sparsely been investigated. Using a functional Magnetic Resonance Imaging (fMRI) paradigm we measured 20 naive subjects during drawing a portrait from a frontal face presented as a photograph. Participants were asked to draw the portrait in either a naturalistic or a sketchy characteristic way. Tracing the contours of the face with a pencil or passive viewing of the face served as control conditions. Compared to passive viewing, naturalistic and sketchy drawing recruited predominantly the dorsal visual pathway, somatosensory and motor areas and bilateral BA 44. The right occipital lobe, middle temporal (MT) and the fusiform face area were increasingly active during drawing compared to passive viewing as well. Compared to tracing with a pencil, both drawing tasks increasingly involved the bilateral precuneus together with the cuneus and right inferior temporal lobe. Overall, our study identified cerebral areas characteristic for previously proposed aspects of drawing: face perception and analysis (fusiform gyrus and higher visual areas), encoding and retrieval of locations in an allocentric reference frame (precuneus), and continuous feedback processes during motor output (parietal sulcus, cerebellar hemisphere).

The method of joint drawing in the practice of teaching drawing to the elementary school children with autism spectrum disorders

Directory of Open Access Journals (Sweden)

Belyalova O.A.

2015-06-01

Full Text Available While teaching children with autism spectrum disorders how to draw the teacher needs to focus on the fact that each child has creative potential and art activities play important part in the brain development. Often children diagnosed with autism spectrum disorder have serious speech impairments, for example, they can talk to parents and family members, but not to classmates and teachers. In that case, one can communicate with a child through drawings, and to access their mood and desires through them. The article describes the method of joint drawing during teaching elementary school children with autism spectrum disorders from the school at the Center for Psychological, Medical and Social Support to Children and Adolescents.

Drawing conclusions: The effect of instructions on children's confabulation and fantasy errors.

Science.gov (United States)

Macleod, Emily; Gross, Julien; Hayne, Harlene

2016-01-01

Drawing is commonly used in forensic and clinical interviews with children. In these interviews, children are often allowed to draw without specific instructions about the purpose of the drawing materials. Here, we examined whether this practice influenced the accuracy of children's reports. Seventy-four 5- and 6-year-old children were interviewed one to two days after they took part in an interactive event. Some children were given drawing materials to use during the interview. Of these children, some were instructed to draw about the event, and some were given no additional instructions at all. Children who were instructed to draw about the event, or who were interviewed without drawing, made few errors. In contrast, children who drew without being given specific instructions reported more errors that were associated with both confabulation and fantasy. We conclude that, to maximise accuracy during interviews involving drawing, children should be directed to draw specifically about the interview topic.

Analysis of the Variations in Rock Magnetic Properties of the Quaternary Blackwater Draw (Eolian) Formation, West Texas

Science.gov (United States)

Stine, J. M.; Ferguson, J. F.; Geissman, J. W.; Sweet, D. E.

2017-12-01

The Quaternary Blackwater Draw Formation consists of the surficial deposits ( 10 + m thick) that directly overlie the Neogene Ogallala Formation in the Southern High Plains (SHP). These Quaternary deposits display a rhythmic pattern where eolian derived sediments (loess) are in turn punctuated by several paleosol layers, implying that Quaternary glacial-interglacial climate cycles are recorded in the Blackwater Draw Formation. In order to investigate this hypothesis, several rock magnetic parameters obtained from the Blackwater Draw Formation were analyzed using exploratory data analysis (EDA) techniques. The Blackwater Draw Formation was sampled at high resolution (2.5-5 cm intervals in depth, which serves as a proxy for time). Rock magnetic parameters measured are bulk magnetic susceptibility (χ, median: 1.56 * 10-4 SI volume), anhysteretic remanent magnetization (ARM, median: 0.1612 A/m), and isothermal remanent magnetization (IRM, median: 2.5367 A/m) intensity, which allow for the determination of two common environmental magnetic ratios (ARM/χ and ARM/IRM, medians: 1051 and 0.068 respectively) that are often used to approximate magnetic grain size. The data were analyzed using robust EDA methods for classification, correlation, and signal extraction. Using these techniques, it becomes evident that a good correspondence exists between the geophysical data and the geologic model (stratigraphy). For example, the cross plots showed that the magnetic data segregate into clusters corresponding to stratigraphy. Smoothing of the magnetic ratio data produces an oscillatory signal that may correspond to climate cyclicity. Additionally the smoothed models show a noticeable change in periodicity, where the ARM, IRM and χ values in the uppermost section exhibit a much higher amplitude and lower frequency than the bottom part of the section (with the reverse being true for the ratios). When comparing the data to the geologic model this change appears to correlate with

Pediatric blood volumes: a one-page reference guide.

Science.gov (United States)

Smiley, J; Reitan, J

1998-10-01

At our institution, a multidisciplinary team met to work out a blood volume policy for our pediatric patients' laboratory testing. Because we are a cancer center, many of our patients are on protocols and/or are in the hospital for an extended period of time. These factors result in multiple blood draws. It is important to manage the volumes used so that we do not compromise the hematological status of our pediatric patients. The concerns of nurses and laboratory technologists were discussed and a three-tiered system was designed consisting of adult volumes, volumes for inflexibility to verify or add to the original order without resticking the patient increase at each tier. It is imperative to the overall quality of care for all patients that discretion is used when following these guidelines. When it is medically prudent to restrict the blood volumes taken from any patient, it should be done. However, when it is not medically necessary, the increased costs and potential decrease in the quality of laboratory service outweighs the desire to use smaller blood volumes.

Human figure drawings by children with Duchenne's muscular dystrophy.

Pope-Grattan, M M; Burnett, C N; Wolfe, C V

1976-02-01

Seventy-two human figure drawings by forty-three patients who had a diagnosis of Duchenne's muscular dystrophy were examined. The study includes a description of these human figure drawings according to eleven emotional indicators and according to directionality quadrants. When the human figure drawings were used as a projective tool, four personality traits of some of the children were identified: physical inadequacy, immaturity, body anxiety, and insecurity. Both the emotional indicators and the quadrant in which the figures appeared were examined in relation to stages of the disease process to see if the human figure drawings of the children might reflect more stress and anxiety at a particular stage of the disease. Suggestions for improvements and recommendations for future study are given.

Experience sharing, emotional reciprocity, and turn-taking

Directory of Open Access Journals (Sweden)

Melisa eStevanovic

2015-04-01

Full Text Available In this perspective article, we consider the relationship between experience sharing and turn-taking. There is much evidence suggesting that human social interaction is permeated by two temporal organizations: (1 the sequential framework of turn-taking and (2 the concurrent framework of emotional reciprocity. From this perspective, we introduce two alternative hypotheses about how the relationship between experience sharing and turn-taking could be viewed. According to the first hypothesis, the home environment of experience sharing is in the concurrent framework of emotional reciprocity, while the motivation to share experiences is in tension with the sequential framework of turn-taking. According to the second hypothesis, then again, people’s inclination to coordinate their actions in terms of turn-taking is motivated precisely by their propensity to share experiences. We consider theoretical and empirical ideas in favor of both of these hypotheses and discuss their implications for future research.

Perceived unfairness at work, social and personal resources, and resting blood pressure.

Science.gov (United States)

Ford, Michael T

2014-02-01

By drawing from theoretical perspectives suggesting that unfair conditions threaten fundamental psychological needs, perceived unfairness at work was proposed and tested as a predictor of resting blood pressure. As part of the Midlife Development in the United States Biomarkers project, participants completed questionnaires measuring perceived unfairness, self-esteem and coworker support. Resting blood pressure readings were also recorded as part of a larger physical examination. Results indicate that perceived unfairness at work was associated with higher resting diastolic and systolic blood pressure. Perceived unfairness was most strongly related to diastolic and systolic blood pressure among women with low levels of coworker support. Contrary to predictions, self-esteem did not moderate the association between perceived unfairness and blood pressure. These results suggest that high blood pressure may be a mechanism linking unfairness to negative health outcomes and point to coworker support as a moderator of the perceived unfairness-blood pressure relationship among women. Further research is needed exploring the mediating mechanisms linking unfair treatment at work to blood pressure and health. Copyright © 2013 John Wiley & Sons, Ltd.

Turning for Ulcer Reduction (TURN) Study: An Economic Analysis.

Paulden, Mike; Bergstrom, Nancy; Horn, Susan D; Rapp, Mary; Stern, Anita; Barrett, Ryan; Watkiss, Michael; Krahn, Murray

2014-01-01

The Turning for Ulcer Reduction (TURN) study was a multisite, randomized controlled trial that aimed to determine the optimal frequency of turning nursing facility residents with mobility limitations who are at moderate and high risk for pressure ulcer (PrU) development. Here we present data from the economic analysis. This economic analysis aims to estimate the economic consequences for Ontario of switching from a repositioning schedule of 2-hour intervals to a schedule of 3-hour or 4-hour intervals. Costs considered in the analysis included those associated with nursing staff time spent repositioning residents and with incontinent care supplies, which included briefs, barrier cream, and washcloths. The total economic benefit of switching to 3-hour or 4-hour repositioning is estimated to be $11.05 or $16.74 per day, respectively, for every resident at moderate or high risk of developing PrUs. For a typical facility with 123 residents, 41 (33%) of whom are at moderate or high risk of developing PrUs, the total economic benefit is estimated to be $453 daily for 3-hour or $686 daily for 4-hour repositioning. For Ontario as a whole, assuming that there are 77,933 residents at 634 LTC facilities, 25,927 (33%) of whom are at moderate or high risk of developing PrUs, the total economic benefits of switching to 3-hour or 4-hour repositioning are estimated to be $286,420 or $433,913 daily, respectively, equivalent to $104.5 million or $158.4 million per year. We did not consider the savings the Ontario Ministry of Health and Long-Term Care might incur should less frequent repositioning reduce the incidence of work-related injury among nursing staff, so our findings are potentially conservative. A switch to 3-hour or 4-hour repositioning appears likely to yield substantial economic benefits to Ontario without placing residents at greater risk of developing PrUs.

On the use of drawing tasks in neuropsychological assessment.

Science.gov (United States)

Smith, Alastair D

2009-03-01

Drawing tasks have attained a central position in neuropsychological assessment and are considered a rich source of information about the presence (or absence) of cognitive and perceptuo-motor abilities. However, unlike other tests of cognitive impairment, drawing tasks are often administered without reference to normative models of graphic production, and their results are often analyzed qualitatively. I begin this article by delineating the different ways in which drawing errors have been used to indicate particular functional deficits in neurological patients. I then describe models of drawing that have been explicitly based on the errors observed in patient drawings. Finally, the case is made for developing a more sensitive set of metrics in order to quantitatively assess patient performance. By providing a finer grain of analysis to assessment we will not only be better able to characterize the consequences of cognitive dysfunction, but may also be able to more subtly characterize and dissociate patients who would otherwise have been placed in the same broad category of impairment.

Primordial spectra from sudden turning trajectory

Science.gov (United States)

Noumi, Toshifumi; Yamaguchi, Masahide

2013-12-01

Effects of heavy fields on primordial spectra of curvature perturbations are discussed in inflationary models with a sudden turning trajectory. When heavy fields are excited after the sudden turn and oscillate around the bottom of the potential, the following two effects are generically induced: deformation of the inflationary background spacetime and conversion interactions between adiabatic and isocurvature perturbations, both of which can affect the primordial density perturbations. In this paper, we calculate primordial spectra in inflationary models with sudden turning potentials taking into account both of the two effects appropriately. We find that there are some non-trivial correlations between the two effects in the power spectrum and, as a consequence, the primordial scalar power spectrum has a peak around the scale exiting the horizon at the turn. Though both effects can induce parametric resonance amplifications, they are shown to be canceled out for the case with the canonical kinetic terms. The peak feature and the scale dependence of bispectra are also discussed.

A new technique for drawing stainless pipes on a mandrel has been developed at the Ural Polytechnical Institute. The method involves metal surfacing with a salt melt and results in stretching equal to 2.0. The use of such metal coats as lubrication sublayers makes possible repeated drawing with and without a mandrel. In both cases, the process does not involve intermediate heat treatment and/or any additional preparation of the surface

2014-06-01

Paediatric dentistry requires knowledge of preventive measures, restorative skills and an understanding of child development. This exploratory, descriptive and qualitative study has analysed children's drawings regarding their perception of dental treatment and oral health. Children aged from six to ten years attending a dental school for treatment were randomly invited to create a drawing about 'dental treatment' and 'oral health'. Verbal expressions made by the children whilst drawing were also recorded and attached to the drawings. These representations were analysed and categorised using Vygotsky postulations for context reading. During the drawing analysis different themes emerged. Five categories regarding perceptions of dental treatment were identified: personal relationship; power relation; trauma; childhood resistance; and contextualisation of dental care in the child's life. Three categories relating to oral health were determined: dichotomy of health/sickness; ludic representation of health; and sickness seen as a process. Drawing can be used to understand children's emotions and expectations about dental treatment. Besides possessing technical skills and scientific knowledge, dentists have an obligation to pay attention to children's feelings.

eulerAPE: drawing area-proportional 3-Venn diagrams using ellipses.

Science.gov (United States)

Micallef, Luana; Rodgers, Peter

2014-01-01

Venn diagrams with three curves are used extensively in various medical and scientific disciplines to visualize relationships between data sets and facilitate data analysis. The area of the regions formed by the overlapping curves is often directly proportional to the cardinality of the depicted set relation or any other related quantitative data. Drawing these diagrams manually is difficult and current automatic drawing methods do not always produce appropriate diagrams. Most methods depict the data sets as circles, as they perceptually pop out as complete distinct objects due to their smoothness and regularity. However, circles cannot draw accurate diagrams for most 3-set data and so the generated diagrams often have misleading region areas. Other methods use polygons to draw accurate diagrams. However, polygons are non-smooth and non-symmetric, so the curves are not easily distinguishable and the diagrams are difficult to comprehend. Ellipses are more flexible than circles and are similarly smooth, but none of the current automatic drawing methods use ellipses. We present eulerAPE as the first method and software that uses ellipses for automatically drawing accurate area-proportional Venn diagrams for 3-set data. We describe the drawing method adopted by eulerAPE and we discuss our evaluation of the effectiveness of eulerAPE and ellipses for drawing random 3-set data. We compare eulerAPE and various other methods that are currently available and we discuss differences between their generated diagrams in terms of accuracy and ease of understanding for real world data.

Kantian Turning Point in Gadamer's Philosophical Hermeneutics

Directory of Open Access Journals (Sweden)

2016-11-01

Full Text Available The paper is treating the theme of a Kantian turning-point in the philosophical hermeneutics of H.- G. Gadamer based on of the harmonic relationship between metaphysics and science in Kantian philosophy from the point of view of the philosophical hermeneutics of Gadamer. The philosophical work of Kant had such an influence on Gadamer that without exaggerating we can talk about the Kantian turning-point in Gadamerian hermeneutics. Grondin, a former student of Gadamer, is talking about Kantian turning-point on the field of aesthetics, but in reality Kantian turning-point means much more than a mere change in the reception of the concept of judgement. It is a discovery of harmonical relationship between the beauty and the moral, between the reason and the sensitivity, between the modern sciences and the metaphysical tradition in the Kantian philosophy, made by Gadamer. This is what we call the Kantian turning-point in Gadamerian hermeneutics.

2011-01-01

The mainstay of diagnosis of relapsing fever (RF) is demonstration of the spirochetes in Giemsa-stained thick blood smears, but during non fever periods the bacteria are very scanty and rarely detected in blood smears by microscopy. This study is aimed to evaluate the sensitivity of different methods developed for detection of low-grade spirochetemia. Animal blood samples with low degrees of spirochetemia were tested with two PCRs and a nested PCR targeting flaB, GlpQ, and rrs genes. Also, a centrifuged-based enrichment method and Giemsa staining were performed on blood samples with various degrees of spirochetemia. The flaB-PCR and nested rrs-PCR turned positive with various degrees of spirochetemia including the blood samples that turned negative with dark-field microscopy. The GlpQ-PCR was positive as far as at least one spirochete was seen in 5-10 microscopic fields. The sensitivity of GlpQ-PCR increased when DNA from Buffy Coat Layer (BCL) was used as template. The centrifuged-based enrichment method turned positive with as low concentration as 50 bacteria/ml blood, while Giemsa thick staining detected bacteria with concentrations ≥ 25000 bacteria/ml. Centrifuged-based enrichment method appeared as much as 500-fold more sensitive than thick smears, which makes it even superior to some PCR assays. Due to simplicity and minimal laboratory requirements, this method can be considered a valuable tool for diagnosis of RF in rural health centers.

Magnesium sheets offer high specific properties which make them very attractive in modern light weight constructions. The main obstacles for a wider usage are their high production costs, the poor corrosion properties and the limited ductility. Until today, forming processes have to be conducted at temperatures well above T=220 C. In the first place, this is a cost factor. Moreover, technical aspects, such as grain growth or the limited use of lubrication speak against high temperatures. The first aim of the presented research work is to increase the ductility at lower temperatures by alloy modification and by an adapted rolling technology. The key factor to reach isotropic mechanical properties and increased limit drawing ratios in deep drawing tools, is to achieve fine, homogeneous microstructures. This can be done by cross rolling at moderate temperatures. The heat treatment has to be adapted accordingly. In a second stage, hydro-mechanical deep drawing experiments were carried out at elevated temperature. The results show that the forming behaviour of the tested Mg-alloys is considerably improved compared to conventional deep drawing. (orig.)

Carver, Donald E.; McAllister, David F.

1991-08-01

With recent advances in 3-D technology, computer users have the opportunity to work within a natural 3-D environment; a flat panel LCD computer display of this type, the DTI-100M made by Dimension Technologies, Inc., recently went on the market. In a joint venture between DTI and NCSU, an object-oriented 3-D drawing application, 3-D Draw, was developed to address some issues of human interface design for interactive stereo drawing applications. The focus of this paper is to determine some of the procedures a user would naturally expect to follow while working within a true 3-D environment. The paper discusses (1) the interface between the Macintosh II and DTI-100M during implementation of 3-D Draw, including stereo cursor development and presentation of current 2-D systems, with an additional `depth'' parameter, in the 3-D world, (2) problems in general for human interface into the 3-D environment, and (3) necessary functions and/or problems in developing future stereoscopic 3-D operating systems/tools.

Bio-responsive polymer architectures can empower medical therapies by engaging molecular feedback-response mechanisms resembling the homeostatic adaptation of living tissues to varying environmental constraints. Here we show that a blood coagulation-responsive hydrogel system can deliver heparin in amounts triggered by the environmental levels of thrombin, the key enzyme of the coagulation cascade, which--in turn--becomes inactivated due to released heparin. The bio-responsive hydrogel quantitatively quenches blood coagulation over several hours in the presence of pro-coagulant stimuli and during repeated incubation with fresh, non-anticoagulated blood. These features enable the introduced material to provide sustainable, autoregulated anticoagulation, addressing a key challenge of many medical therapies. Beyond that, the explored concept may facilitate the development of materials that allow the effective and controlled application of drugs and biomolecules.

duration of cry was significantly shorter than in controls, but pain perception did not significantly differ between these groups. As expected, the duration of the entire process was shortest in the control group (5.0 ± 3.8 min), moderate with clown (19.3 ± 5.8 min), and longest with EMLA (63.2 ± 11.4 min, p anxiety related to future blood tests as evaluated by telephone the following day revealed that it was significantly lower with clown than in the control group or EMLA (2.6 ± 1.2 vs 3.7 ± 1.3 or 3.8 ± 1.6, p children undergoing blood tests or line insertion. Although pain reduction was better with EMLA, both duration of cry and anxiety were lower with a medical clown. These results strongly encourage and support the utilization of medical clowns while drawing blood in children.

Creating a recollection-based memory through drawing.

Drawing a picture of to-be-remembered information substantially boosts memory performance in free-recall tasks. In the current work, we sought to test the notion that drawing confers its benefit to memory performance by creating a detailed recollection of the encoding context. In Experiments 1 and 2, we demonstrated that for both pictures and words, items that were drawn by the participant at encoding were better recognized in a later test than were words that were written out. Moreover, participants' source memory (in this experiment, correct identification of whether the word was drawn or written) was superior for items drawn relative to written at encoding. In Experiments 3A and 3B, we used a remember-know paradigm to demonstrate again that drawn words were better recognized than written words, and further showed that this effect was driven by a greater proportion of recollection-, rather than familiarity-based responses. Lastly, in Experiment 4 we implemented a response deadline procedure, and showed that when recognition responses were speeded, thereby reducing participants' capacity for recollection, the benefit of drawing was substantially smaller. Taken together, our findings converge on the idea that drawing improves memory as a result of providing vivid contextual information which can be later called upon to aid retrieval.

Park, Dong Hwan; Yarlagadda, Prasad K. D. V.

2004-06-01

In general, deep drawing products have various cross-section shapes such as cylindrical, rectangular and non-axisymmetric shapes. The application of the surface area calculation to non-axisymmetric deep drawing process has not been published yet. In this research, a surface area calculation for non-axisymmetric deep drawing products with elliptical shape was constructed for a design of blank shape of deep drawing products by using an AutoLISP function of AutoCAD software. A computer-aided process planning (CAPP) system for rotationally symmetric deep drawing products has been developed. However, the application of the system to non-axisymmetric components has not been reported yet. Thus, the CAPP system for non-axisymmetric deep drawing products with elliptical shape was constructed by using process sequence design. The system developed in this work consists of four modules. The first is recognition of shape module to recognize non-axisymmetric products. The second is a three-dimensional (3-D) modeling module to calculate the surface area for non-axisymmetric products. The third is a blank design module to create an oval-shaped blank with the identical surface area. The forth is a process planning module based on the production rules that play the best important role in an expert system for manufacturing. The production rules are generated and upgraded by interviewing field engineers. Especially, the drawing coefficient, the punch and die radii for elliptical shape products are considered as main design parameters. The suitability of this system was verified by applying to a real deep drawing product. This CAPP system constructed would be very useful to reduce lead-time for manufacturing and improve an accuracy of products.

Science required the recording of data to build knowledge. The act of drawing an illustration is one of the oldest methods to record the data in science. Illustration in science provides information that the written word cannot, hence the old adage “A picture is worth a thousand words” is very important for studying science. Drawings an illustration is not only valuable for artists but also for scientists because some aspects of science process skills can also be developed through drawing. In terms of science teaching, applying the act of drawing can also be used as an assessment tool. In this study, we assessed drawing of human internal organs of 38 student teachers who enrolled human physiology course and its correlation to their final exam achievement. Guidance of biological drawing was employed to assess the quality, labelling, and annotations of the drawing. The finding of this study showed that there was a positive correlation between the quality of drawing and final exam achievement. It is suggested that using the method of drawing in combination with written responses assessment would provide a more complete information about student’s understanding of human internal organs.

Full Text Available The purpose of this study is to investigate the variation of the required punch load during the deep drawing process under different friction conditions. In this regards, several deep-drawing tests of cylindrical cups were conducted under four friction conditions at the tool–blank interface. The first case was the dry deep-drawing, considered as a reference friction condition, while in the other three cases hydraulic oil, lithium-based grease and animal fat were used as lubricants. For each friction case, three levels of blank holding force were adopted, namely 10, 20 and 25 kN. The finite element simulation of the deep-drawing process was used to generate a set of calibration curves. By overlapping the experimental load-stroke curves on the calibration curves, the friction coefficient was estimated for each friction case.

Procedures involving phlebotomy are critical for obtaining diagnostic blood specimens and represent a well known and recognized problem, probably among the most important issues in laboratory medicine. The aim of this report is to show spurious hyperkalemia and hypocalcemia due to inadequate phlebotomy procedure. The diagnostic blood specimens were collected from a male outpatient 45 years old, with no clinical complaints. The tubes drawing order were as follows: i) clot activator and gel separator (serum vacuum tube), ii) K3EDTA, iii) a needleless blood gas dedicated-syringe with 80 I.U. lithium heparin, directly connected to the vacuum tube holder system. The laboratory testing results from serum vacuum tube and dedicated syringe were 4.8 and 8.5 mmol/L for potassium, 2.36 and 1.48 mmol/L for total calcium, respectively. Moreover 0.15 mmol/L of free calcium was observed in dedicated syringe. A new blood collection was performed without K3EDTA tube. Different results were found for potassium (4.7 and 4.5 mmol/L) and total calcium (2.37 and 2.38 mmol/L) from serum vacuum tube and dedicated syringe, respectively. Also free calcium showed different concentration (1.21 mmol/L) in this new sample when compared with the first blood specimen. Based on this case we do not encourage the laboratory managers training the phlebotomists to insert the dedicated syringes in needle-holder system at the end of all vacuum tubes. To avoid double vein puncture the dedicated syringe for free calcium determination should be inserted immediately after serum tubes before EDTA vacuum tubes. PMID:23894868

Children's developing ability to depict emotions in their drawings.

55 children aged 5 to 9 years were asked to draw pictures depicting happiness, sadness, anger, surprise, and fear as well as pictures that did not express any emotion. These pictures were then scored by nonexpert adults for their overall emotional expressiveness, that is, how well they depicted the intended emotion. The results showed that drawings were generally regarded by adults as emotionally expressive. Happiness was the emotion most easily recognized in children's drawings, closely followed by sadness. The results also showed a linear increase in ratings of emotional expressiveness with age.

The formation of beta-turns in globular proteins has been studied by the method of molecular mechanics. Statistical method of discriminant analysis was applied to calculate energy components and sequences of oligopeptide segments, and after this prediction of I type beta-turns has been drawn. The accuracy of true positive prediction is 65%. Components of conformational energy considerably affecting beta-turn formation were delineated. There are torsional energy, energy of hydrogen bonds, and van der Waals energy.

New method for rapid Susceptibility Testing on blood culture with HB&L system: preliminary data

Directory of Open Access Journals (Sweden)

Vincenzo Rondinelli

2010-12-01

Full Text Available Blood culture, although represents the gold standard in detecting the ethiological agent of sepsis, is rather rarely required in relation to the real diagnostic importance. The result of this test depends in fact on many factors (sample volume, time of collection, accuracy, antibiotic therapy, contamination, number of drawings, drawing site, interpretation difficulties, etc. that are often considered by many clinicians so limited as to doubt about their actual value. The disadvantages are therefore represented by the lack of standardization but also by the low sensitivity and above all by the technical times too long for the clinical needs. Blood culture begins with the drawing of samples from the “septic” patient followed incubation of the bottles in automatic thermostated systems. In case of positive result (36 hours, the culture is Gram stained and streaked on solid media in order to obtain isolated colonies for the identification and the susceptibility testing (48 hours from positive result. The long time required for pathogen identification and susceptibility testing involves empirical broad spectrum antibiotic therapy that can promote the increase of bacterial resistance but also patient management costs. A clinically useful report should be available on short notice in order to guide the clinician to choose the most appropriate antibiotic. The microbiologist has therefore the hard work of reviewing the organization and the management of the procedures.We have therefore started to consider the possibility of treating the blood as an biological liquid in order to quickly determine the susceptibility of bacteria to antibiotics.

This article examines the process of rebuilding institutional trust in the Canadian blood system in the aftermath of the tainted blood scandal. Our focus is the policy of lifetime deferral from donating blood for men who have sex with men. Drawing on findings from interviews with representatives of Health Canada's Expert Advisory Committee on Blood Regulation, the National Liaison Committee, Canadian Blood Services, and blood consumer groups, we demonstrate how claims making about rights, discrimination, science, and risk contribute to policy continuity. We also examine the link between policy continuity and the management of reputational risk.

Comfort drawing during investigative interviews: evidence of the safety of a popular practice.

Science.gov (United States)

Poole, Debra Ann; Dickinson, Jason J

2014-02-01

This study evaluated the impact of comfort drawing (allowing children to draw during interviews) on the quality of children's eyewitness reports. Children (N=219, 5 to 12 years) who had participated in an earlier memory study returned 1 or 2 years later, experienced a new event, and described these events during phased, investigative-style interviews. Interviewers delivered the same prompts to children in the no drawing and drawing conditions but provided paper and markers in the drawing condition, invited these children to draw, and periodically asked if they would like to make another picture. Most children in the drawing condition were interested in using the materials, and measures of eyewitness performance were sensitive to differences in cognitive ability (i.e., age) and task difficulty (i.e., delay between the remote event and interview). Comfort drawing had no overall impact as evidenced by nonsignificant main effects of condition across 20 performance measures, although more of the younger children reported experienced touching in the drawing than no drawing condition. The children successfully divided attention between voluntary drawing and conversations about past events. Importantly, comfort drawing did not impair the amount of information recalled, the accuracy of children's answers, or even the extent to which interviewers needed to prompt for answers. Due to the large number of analyses, the benefit of drawing for younger, touched children requires replication. Comfort drawing poses no documented risks for typically-developing school-aged children, but the practice remains untested for younger children and those with cognitive impairments.

Wammes, Jeffrey D; Meade, Melissa E; Fernandes, Myra A

2017-09-01

Traditionally, students adopt the strategy of taking written notes when attending a class or learning from a textbook in educational settings. Informed by previous work showing that learning by doing improves memory performance, we examined whether drawing to-be-remembered definitions from university textbooks would improve later memory, relative to a more typical strategy of rote transcription. Participants were asked to either write out the definition, or to draw a picture representative of the definition. Results indicated that drawing, relative to verbatim writing, conferred a reliable memorial benefit that was robust, even when participants' preexisting familiarity with the terms was included as a covariate (in Experiment 1) or when the to-be-remembered terms and definitions were fictitious, thus removing the influence of familiarity (in Experiment 2). We reasoned that drawing likely facilitates retention at least in part because at encoding, participants must retain and elaborate upon information regarding the meaning of the definition, to translate it into a new form (a picture). This is not the case when participants write out the definitions verbatim. In Experiment 3 we showed that paraphrasing during encoding, which, like drawing and in contrast with verbatim writing, requires self-generated elaboration, led to memory performance that was comparable to drawing. Taken together, results suggest that drawing is a powerful tool which improves memory, and that drawing produces a similar level of retention as does paraphrasing. This suggests that elaborative encoding plays a critical role in the memorial benefit that drawing confers to memory for definitions of academic terms. Copyright © 2017 Elsevier B.V.

Inverse Analysis to Formability Design in a Deep Drawing Process

Science.gov (United States)

Buranathiti, Thaweepat; Cao, Jian

Deep drawing process is an important process adding values to flat sheet metals in many industries. An important concern in the design of a deep drawing process generally is formability. This paper aims to present the connection between formability and inverse analysis (IA), which is a systematical means for determining an optimal blank configuration for a deep drawing process. In this paper, IA is presented and explored by using a commercial finite element software package. A number of numerical studies on the effect of blank configurations to the quality of a part produced by a deep drawing process were conducted and analyzed. The quality of the drawing processes is numerically analyzed by using an explicit incremental nonlinear finite element code. The minimum distance between elemental principal strains and the strain-based forming limit curve (FLC) is defined as tearing margin to be the key performance index (KPI) implying the quality of the part. The initial blank configuration has shown that it plays a highly important role in the quality of the product via the deep drawing process. In addition, it is observed that if a blank configuration is not greatly deviated from the one obtained from IA, the blank can still result a good product. The strain history around the bottom fillet of the part is also observed. The paper concludes that IA is an important part of the design methodology for deep drawing processes.

Relevance of EDTA carryover during blood collection.

The order of draw is regarded as a preanalytical issue to prevent carryover of additives during blood collection. Our objective was to prove the theory of ethylenediaminetetraacetic acid (EDTA) carryover for a closed vacuum system and the influence of EDTA on concentrations of selected biomarkers. To test the carryover of EDTA, a blood collection with tripotassium EDTA (K3EDTA) and subsequent non-additive tubes was simulated using distilled water as substitute for blood. EDTA concentrations were measured by tandem mass spectrometry. Then we added increasing concentrations of EDTA to heparinized blood and measured routine biomarkers, thereby simulating a carryover of EDTA whole blood and pure EDTA, respectively. Additionally, we tested for EDTA contamination and biomarker alteration in samples collected from 10 healthy volunteers by a syringe with subsequent transfer into sample tubes. No EDTA contamination was detected in samples collected subsequent to a K3EDTA tube when adhering to guidelines of blood sampling. Magnesium, calcium, and potassium levels were altered by artificial K3EDTA whole-blood contamination as well as when adding 1 μL pure K3EDTA. Iron values were altered at EDTA concentrations of 4.4 mmol/L. All other parameters remained unaffected. A slight EDTA carryover was observed in syringe collection and subsequent transfer into EDTA and heparin tubes, however, without any biomarker alteration. An EDTA carryover during blood collection using a closed vacuum system is highly unlikely. Even if carryover of EDTA whole blood occurs, an absolute volume larger than 10 μL would be necessary to alter test results. However, contamination of samples with preloaded pure K3EDTA solution by severe neglect of current recommendations in blood collection may significantly alter testing results.

Stafstrom, Carl E; Havlena, Janice

2003-02-01

Epilepsy is a chronic disorder that is associated with numerous psychological challenges, especially in children. Drawings have been underutilized as a method to obtain insight into psychological issues in children with epilepsy. We asked 105 children with epilepsy, ages 5 to 18 years, to draw a picture of what it is like to have a seizure. Across ages and epilepsy syndromes, the drawings showed evidence of impaired self-concept, low self-esteem, and a sense of helplessness and vulnerability. Overall, the drawings of human figures were less developed than expected for chronological age. In some drawings, indicators of underlying depression were found. When considered by epilepsy syndrome or seizure type, some specific artistic features were noted. Children with simple partial (motor) seizures drew distorted body parts, especially limbs. Those with complex partial seizures depicted sensory symptoms and mental status changes such as confusion. Children with generalized tonic-clonic seizures showed shaking extremities. Drawings by children with absence seizures illustrated mainly staring. In conclusion, drawings are a powerful method to examine the self-concept of children with epilepsy and gain insight into their feelings about themselves and their world.

Spatially discrete thermal drawing of biodegradable microneedles for vascular drug delivery.

2013-02-01

Spatially discrete thermal drawing is introduced as a novel method for the fabrication of biodegradable microneedles with ultra-sharp tip ends. This method provides the enhanced control of microneedle shapes by spatially controlling the temperature of drawn polymer as well as drawing steps and speeds. Particular focus is given on the formation of sharp tip ends of microneedles at the end of thermal drawing. Previous works relied on the fracture of polymer neck by fast drawing that often causes uncontrolled shapes of microneedle tips. Instead, this approach utilizes the surface energy of heated polymer to form ultra-sharp tip ends. We have investigated the effect of such temperature control, drawing speed, and drawing steps in thermal drawing process on the final shape of microneedles using biodegradable polymers. XRD analysis was performed to analyze the effect of thermal cycle on the biodegradable polymer. Load-displacement measurement also showed the dependency of mechanical strengths of microneedles on the microneedle shapes. Ex vivo vascular tissue insertion and drug delivery demonstrated microneedle insertion to tunica media layer of canine aorta and drug distribution in the tissue layer. Copyright © 2012 Elsevier B.V.

2016-06-01

The purpose of this descriptive pilot study was to assess the ability of youth to create a meaningful drawing related to living with type 1 diabetes and explore the benefits of expressing emotion through drawing in future interventional work. Youth aged 4 to 19 years (N = 242) with type I diabetes attending routine follow-up appointments within a pediatric specialty clinic were asked to draw: "If diabetes had a face what would it look like?" Drawings reflected many emotions and ranged from simple to complex in detail. Drawings reflected multiple experiences of living with diabetes including emotions, tools used for management, and effects of self-care. Youth were able to create drawings reflecting their experience of living with diabetes. Youth conveyed a variety of emotions, attitudes, and experiences in drawing the "face" of diabetes. Drawing during clinic visits provides opportunity to explore the unspoken experiences of living with a chronic health condition, which may not be obtained during routine clinical information gathering. Deeper understanding of patient's lived experience may assist providers in therapeutic management.

1976-01-01

The texture of low-carbon steel, molybdenum and tungsten wires subjected to intermediate and finish drawing were studied to find whether it is common to metals with a body-centered lattice. Experimental data tend to indicate that both the intermediate drawing and the finish drawing give rise to two axial textures, or (110) and (114), parallel to the axis of drawing. It was inferred that the mechanism of the formation of texture in drawing is common to all the metals of a VCC lattice

Tomographic reconstruction of transverse phase space from turn-by-turn profile data

CERN Document Server

Hancock, S; Lindroos, M

1999-01-01

Tomographic methods have the potential for useful application in beam diagnostics. The tomographic reconstruction of transverse phase space density from turn-by-turn profile data has been studied with particular attention to the effects of dispersion and chromaticity. It is shown that the modified Algebraic Reconstruction Technique (ART) that deals successfully with the problem of non-linear motion in the longitudinal plane cannot, in general, be extended to cover the transverse case. Instead, an approach is proposed in which the effect of dispersion is deconvoluted from the measured profiles before the phase space picture is reconstructed using either the modified ART algorithm or the inverse Radon Transform. This requires an accurate knowledge of the momentum distribution of the beam and the modified ART reconstruction of longitudinal phase space density yields just such information. The method has been tested extensively with simulated data.

Analysis of children's perception of triatomine vectors of chagas disease through drawings: opportunities for targeted health education.

Science.gov (United States)

Yevstigneyeva, Violetta; Camara-Mejia, Javier; Dumonteil, Eric

2014-10-01

Chagas disease is a tropical parasitic disease affecting about 10 million people, mostly in the Americas, and transmitted mainly by triatomine bugs. Insect vector control with indoor residual insecticides and the promotion of housing improvement is the main control intervention. The success of such interventions relies on their acceptance and appropriation by communities, which depends on their knowledge and perceptions of both the disease and the vector. In this study, we investigated school-aged children's knowledge and perception on triatomine vectors and Chagas disease to further understand how communities view this vector and the disease in Yucatan, Mexico. We performed an analysis of children's drawings on the theme of triatomines and their house in several rural villages, to explore in an open-ended manner their views, understanding and misconceptions. A total of 261 drawings were collected from children ages 6-12 from four villages. We found that children are very familiar with triatomine vectors, and know very well many aspects of their biology and ecology, and in particular their blood-feeding habits. On the other hand, their drawings suggest that the role of triatomines as vectors of a chronic and severe cardiac disease is less understood, and the main perceived health threat appears limited to the bite itself, as previously observed in adults. These results have important implications for the specific design of future education materials and campaigns, and for the promotion of the inclusion of children in raising Chagas disease awareness in these endemic communities.

Children's Recognition of Emotional Facial Expressions Through Photographs and Drawings.

Science.gov (United States)

Brechet, Claire

2017-01-01

The author's purpose was to examine children's recognition of emotional facial expressions, by comparing two types of stimulus: photographs and drawings. The author aimed to investigate whether drawings could be considered as a more evocative material than photographs, as a function of age and emotion. Five- and 7-year-old children were presented with photographs and drawings displaying facial expressions of 4 basic emotions (i.e., happiness, sadness, anger, and fear) and were asked to perform a matching task by pointing to the face corresponding to the target emotion labeled by the experimenter. The photographs we used were selected from the Radboud Faces Database and the drawings were designed on the basis of both the facial components involved in the expression of these emotions and the graphic cues children tend to use when asked to depict these emotions in their own drawings. Our results show that drawings are better recognized than photographs, for sadness, anger, and fear (with no difference for happiness, due to a ceiling effect). And that the difference between the 2 types of stimuli tends to be more important for 5-year-olds compared to 7-year-olds. These results are discussed in view of their implications, both for future research and for practical application.

Manual of engineering drawing to British and international standards

2004-01-01

The Manual of Engineering Drawing has long been recognised as the student and practising engineer's guide to producing engineering drawings that comply with ISO and British Standards. The information in this book is equally applicable to any CAD application or manual drawing. The second edition is fully in line with the requirements of the new British Standard BS8888: 2002, and will help engineers, lecturers and students with the transition to the new standards.BS8888 is fully based on the relevant ISO standards, so this book is also ideal for an international readership.

To investigate the cognitive processes underlying creative inspiration, we tested the extent to which viewing or copying prior examples impacted creative output in art. In Experiment 1, undergraduates made drawings under three conditions: (a) copying an artist's drawing, then producing an original drawing; (b) producing an original drawing without having seen another's work; and (c) copying another artist's work, then reproducing that artist's style independently. We discovered that through copying unfamiliar abstract drawings, participants were able to produce creative drawings qualitatively different from the model drawings. Process analyses suggested that participants' cognitive constraints became relaxed, and new perspectives were formed from copying another's artwork. Experiment 2 showed that exposure to styles of artwork considered unfamiliar facilitated creativity in drawing, while styles considered familiar did not do so. Experiment 3 showed that both copying and thoroughly viewing artwork executed using an unfamiliar style facilitated creativity in drawing, whereas merely thinking about alternative styles of artistic representation did not do so. These experiments revealed that deep encounters with unfamiliar artworks-whether through copying or prolonged observation-change people's cognitive representations of the act of drawing to produce novel artwork.

Line Width Recovery after Vectorization of Engineering Drawings

Full Text Available Vectorization is the conversion process of a raster image representation into a vector representation. The contemporary commercial vectorization software applications do not provide sufficiently high quality outputs for such images as do mechanical engineering drawings. Line width preservation is one of the problems. There are applications which need to know the line width after vectorization because this line attribute carries the important semantic information for the next 3D model generation. This article describes the algorithm that is able to recover line width of individual lines in the vectorized engineering drawings. Two approaches are proposed, one examines the line width at three points, whereas the second uses a variable number of points depending on the line length. The algorithm is tested on real mechanical engineering drawings.

The process of drawing glass rods (light guides) is being studied. The parameters of the process affecting the quality of the light guide have been determined. To solve the problem, mathematical models based on general equations of continuum mechanics are used. The conditions for the stable flow of the drawing process have been found, which are determined by the stability of the motion of the glass mass in the formation zone to small uncontrolled perturbations. The sensitivity of the formation zone to perturbations of the drawing speed and viscosity is estimated. Experimental models of the drawing process, based on the regression analysis methods, have been obtained. These models make it possible to customize a specific production process to obtain light guides of the required quality. They allow one to find the optimum combination of process parameters in the chosen area and to determine the required accuracy of maintaining them at a specified level.
